UNESCO World Heritage & Heritage Sites of Northeast India: State-wise List, Tentative Sites & Cultural Legacy
UNESCO World Heritage Sites of Northeast India represent some of the region's most exceptional natural landscapes, archaeological remains, sacred cultural landscapes and living traditions. From the floodplain grasslands of Kaziranga and the Himalayan foothill forests of Manas to the royal burial mounds of Charaideo and the sacred mountain landscape of Khangchendzonga, Northeast India's heritage reflects an extraordinary relationship between people, nature, history and geography.
The region also contains an important group of properties on India's UNESCO Tentative List. These include the Apatani Cultural Landscape, Thembang Fortified Village, Majuli, Keibul Lamjao Conservation Area, Living Root Bridge Cultural Landscapes, Unakoti, Naga Hill Ophiolite, Meghalayan Age Caves and the recently added Rangpur-Sivasagar Historic Ensemble.
Beyond UNESCO recognition, every Northeastern state contains major historical, archaeological, religious and community heritage places. Tawang Monastery, Sivasagar's Ahom monuments, Kangla, Nartiang Monoliths, Vangchhia, the Kachari ruins of Dimapur, Rabdentse and Neermahal are examples of the wider heritage landscape of the region.
This article provides a state-wise guide to UNESCO and heritage sites of Northeast India, clearly separating properties already inscribed on the World Heritage List from properties that remain on India's Tentative List and from important regional heritage places that do not currently hold UNESCO World Heritage status.

UNESCO World Heritage Sites of Northeast India at a Glance
As of 2026, the eight Northeastern states contain four properties inscribed on the UNESCO World Heritage List.
Three are located in Assam and one is located in Sikkim.
| UNESCO World Heritage Site | State | Year | Category | UNESCO Criteria |
|---|---|---|---|---|
| Kaziranga National Park | Assam | 1985 | Natural | (ix), (x) |
| Manas Wildlife Sanctuary | Assam | 1985 | Natural | (vii), (ix), (x) |
| Khangchendzonga National Park | Sikkim | 2016 | Mixed | (iii), (vi), (vii), (x) |
| Moidams – the Mound-Burial System of the Ahom Dynasty | Assam | 2024 | Cultural | (iii), (iv) |
This distribution is important because Northeast India contains all three principal World Heritage categories: natural heritage, cultural heritage and mixed heritage.
State-wise UNESCO Heritage Status in Northeast India

What Is a UNESCO World Heritage Site?
A UNESCO World Heritage Site is a cultural, natural or mixed property considered to possess Outstanding Universal Value under the World Heritage Convention.
India ratified the World Heritage Convention in 1977.
UNESCO World Heritage properties fall broadly into three categories:
- Cultural: archaeological sites, historic cities, monuments, cultural landscapes and other human-created heritage;
- Natural: ecosystems, landscapes, geological features and biodiversity of exceptional international importance; and
- Mixed: properties possessing both outstanding cultural and natural values.
Northeast India is unusual because its four inscribed properties collectively represent all three categories.
What Is the UNESCO Tentative List?
A UNESCO Tentative List is an inventory of properties that a State Party may consider nominating for inscription on the World Heritage List.
Being placed on the Tentative List is an important step, but it does not guarantee eventual inscription.
A property generally requires detailed documentation of its potential Outstanding Universal Value, integrity or authenticity, protection systems, comparative significance and long-term management before a full World Heritage nomination can succeed.
1. Kaziranga National Park – Assam
Kaziranga National Park was inscribed on the UNESCO World Heritage List in 1985 under natural criteria (ix) and (x).
The UNESCO property covers approximately 42,996 hectares in the Brahmaputra Valley of Assam.
Why Kaziranga Is a World Heritage Site
Kaziranga protects one of the finest remaining examples of the Brahmaputra floodplain ecosystem.
Its landscape contains:
- tall alluvial grasslands;
- shallow wetlands and beels;
- river channels;
- sandbars;
- deciduous woodland; and
- semi-evergreen forest patches.
The landscape is continuously shaped by flooding, sediment deposition and shifting river channels.
One-horned Rhinoceros
Kaziranga is globally famous as a major stronghold of the greater one-horned rhinoceros.
The protected landscape also supports Asian elephants, tigers, wild water buffalo, swamp deer and a remarkable diversity of birds.
Geographical Importance
Kaziranga demonstrates why the floodplain itself is part of the heritage value. Seasonal floods may appear destructive, but they also maintain grasslands, replenish wetlands and sustain ecological processes that support wildlife.
The park therefore represents both biodiversity conservation and the dynamic geomorphology of the Brahmaputra Valley.
2. Manas Wildlife Sanctuary – Assam
Manas Wildlife Sanctuary was also inscribed in 1985 and is recognized under natural criteria (vii), (ix) and (x).
The World Heritage property covers approximately 39,100 hectares.
Landscape of Manas
Manas occupies a remarkable ecological transition zone where the Himalayan foothills descend toward the Assam plains.
The landscape contains:
- forested hills;
- alluvial grasslands;
- tropical evergreen forests;
- river channels; and
- foothill ecosystems.
The Manas River passes through the landscape and helps create an exceptionally diverse mixture of habitats.
Rare and Endangered Wildlife
The sanctuary provides important habitat for wildlife including:
- tiger;
- greater one-horned rhinoceros;
- Asian elephant;
- pygmy hog;
- swamp deer; and
- Bengal florican.
Manas and the World Heritage in Danger List
Manas was placed on the List of World Heritage in Danger from 1992 to 2011.
Its later removal from that list became an important example of how conservation, restoration and improved management can recover the condition of a threatened World Heritage property.
Transboundary Context
Manas lies immediately south of protected forest landscapes in Bhutan. Wildlife, river systems and ecological processes extend across the international boundary, making landscape-level cooperation particularly important.
3. Moidams – the Mound-Burial System of the Ahom Dynasty – Assam
Moidams – the Mound-Burial System of the Ahom Dynasty was inscribed on the UNESCO World Heritage List in 2024 under cultural criteria (iii) and (iv).
The property is located at Charaideo in eastern Assam, near the foothills of the Patkai Ranges.
Royal Necropolis of the Tai-Ahom
Charaideo was associated with the early political and sacred geography of the Tai-Ahom kingdom.
For approximately six centuries, members of the Tai-Ahom royal family were buried in monumental earthen mounds known as moidams.
UNESCO records 90 moidams within the inscribed property.
Structure of a Moidam
A typical royal moidam consists of an earthen mound raised over a burial vault constructed with materials such as brick, stone and earth.
The landscape also contains associated walls, water bodies, vegetation and sacred features.
Rather than functioning simply as isolated tombs, the burial mounds collectively form a carefully structured sacred funerary landscape.
Tai-Ahom Cultural Meaning
The moidams embody Tai-Ahom ideas relating to ancestry, kingship, death and the relationship between the earthly and spiritual worlds.
Traditional rituals associated with ancestors continue to be practiced within the wider Charaideo cultural landscape.
Why the UNESCO Inscription Is Important
The inscription gave international recognition to a form of royal funerary architecture that is strongly associated with the history of Assam but differs substantially from the stone-built royal tomb traditions found elsewhere in India.
It also strengthened the global visibility of the Ahom period and the historical connections between the Brahmaputra Valley and wider Tai cultural traditions of Southeast Asia.
4. Khangchendzonga National Park – Sikkim
Khangchendzonga National Park was inscribed on the UNESCO World Heritage List in 2016.
It is recognized under both cultural and natural criteria—(iii), (vi), (vii) and (x)—and is therefore a Mixed World Heritage Site.
It became India's first property to receive World Heritage status in the mixed category.
Extraordinary Altitudinal Range
The UNESCO property covers approximately 178,400 hectares and rises from around 1,220 metres to the summit region of Mount Khangchendzonga at 8,586 metres.
This extraordinary vertical range produces a sequence of environments extending from lower forests to:
- temperate forests;
- subalpine vegetation;
- alpine meadows;
- glacial landscapes;
- high mountain lakes; and
- permanent snow and ice.
Natural Heritage
The national park lies within the Himalayan biodiversity hotspot and protects habitat for species such as the red panda, snow leopard and numerous Himalayan birds, mammals and plants.
The landscape also contains major glaciers, including the Zemu Glacier, as well as numerous high-altitude lakes and peaks.
Sacred Cultural Landscape
Khangchendzonga is not recognized only for its natural beauty.
The mountain, lakes, caves, rivers and other features form part of a deeply sacred landscape for the indigenous Lepcha people and within Sikkimese Buddhist traditions.
The interaction between natural ecosystems, mythology, sacred geography and living religious beliefs explains why the property qualifies as both cultural and natural heritage.
UNESCO Tentative Sites of Northeast India
The following Northeast Indian properties appear on India's current UNESCO Tentative List.
| Tentative Property | State | Submitted | Category |
|---|---|---|---|
| River Island of Majuli in midstream of Brahmaputra River in Assam | Assam | 2004 | Cultural |
| Namdapha National Park | Arunachal Pradesh | 2006 | Natural |
| Apatani Cultural Landscape | Arunachal Pradesh | 2014 | Cultural |
| Thembang Fortified Village | Arunachal Pradesh | 2014 | Cultural |
| Keibul Lamjao Conservation Area | Manipur | 2016 | Mixed |

| Naga Hill Ophiolite | Nagaland | 2025 | Natural |
| Meghalayan Age Caves | Meghalaya | 2025 | Natural |
| Rangpur-Sivasagar Historic Ensemble | Assam | 2026 | Cultural |
Majuli Cultural Landscape
The River Island of Majuli has remained on India's Tentative List since 2004.
Its importance is not limited to its location within the dynamic Brahmaputra river system. Majuli is also one of the principal centres of Assam's Neo-Vaishnavite culture and contains historic satras that preserve religious performance, manuscript traditions, mask-making, music and other cultural practices.
Namdapha National Park
Namdapha National Park in Arunachal Pradesh was submitted to the Tentative List in 2006 as a natural property.
The UNESCO description emphasizes its mountainous wilderness, the Noa-Dihing catchment and an altitudinal range extending from low tropical environments to high mountains.
Apatani Cultural Landscape
The Apatani Cultural Landscape of Ziro Valley was added in 2014.
Its proposed heritage value centres on a long-established relationship between the Apatani community and the valley environment, including settled agriculture, water management, traditional ecological knowledge and village institutions.
Thembang Fortified Village
Thembang is a Monpa settlement in West Kameng district characterized by traditional fortified architecture.
The UNESCO Tentative List describes the village as a living cultural landscape where architecture, community traditions and the Eastern Himalayan environment remain closely connected.
Keibul Lamjao Conservation Area
The proposed Keibul Lamjao Conservation Area includes the floating landscape of Keibul Lamjao National Park together with parts of Loktak Lake and Pumlen Pat.
The area combines ecological significance with strong cultural and livelihood relationships between the lake and surrounding communities.
It is particularly important as the habitat of the endangered Sangai.
Garo Hills Conservation Area
The Garo Hills Conservation Area is proposed as a mixed property combining natural and cultural values.
Its proposed core includes protected areas such as Nokrek National Park, Balpakram National Park and Siju Wildlife Sanctuary together with other forest landscapes.
The nomination concept also recognizes long-standing relationships between Garo communities, forests, traditional land-use systems and indigenous belief traditions.
Jingkieng Jri: Living Root Bridge Cultural Landscapes
Meghalaya's famous Living Root Bridges, locally known as Jingkieng Jri, were added to India's Tentative List in 2022.
These living structures are created by guiding and training the aerial roots of Ficus trees across streams and ravines.
The tradition represents an unusual form of nature-based engineering developed and maintained across generations by Khasi communities.
UNESCO's Tentative List documentation identifies living root structures across more than 75 villages and emphasizes their role in connectivity, ecological restoration and resilience under extremely high rainfall conditions.
Unakoti Rock-cut Sculptures
Unakoti in Tripura was added to India's Tentative List in 2022.
The site contains monumental rock-cut reliefs and freestanding sculptures associated largely with Shaiva traditions.
UNESCO documentation broadly dates important parts of the complex to around the 8th–9th centuries CE.
The colossal image known as Unakotiswara Kala Bhairava is the best-known feature of the archaeological landscape.
Naga Hill Ophiolite
The Naga Hill Ophiolite entered India's Tentative List in 2025.
Ophiolites are fragments of ancient oceanic crust and upper mantle that became incorporated into continental mountain systems through tectonic processes.
The Naga Hill occurrence is therefore important for understanding the geological evolution of the Indo-Myanmar ranges and plate convergence along India's eastern margin.
Meghalayan Age Caves
The Meghalayan Age Caves were added to India's Tentative List in 2025.
The proposal includes Mawmluh, Arwah, Mawsmai and Krem Puri caves.
Mawmluh Cave is globally significant because a stalagmite record from the cave provided the reference used in defining the Meghalayan Age of the Holocene geological timescale.
The property therefore links Northeast India's cave landscape with global geological chronology.
Rangpur-Sivasagar Historic Ensemble
The Rangpur-Sivasagar Historic Ensemble became one of India's newest Tentative List entries in 2026.
The proposed cultural landscape contains the architectural and hydraulic legacy of the later Ahom period, including palatial, ceremonial, religious and water-management structures.
Important features include Rang Ghar, Talatal Ghar, major historic tanks, temples, roads and other surviving structures associated with Ahom statecraft and urban planning.
Heritage Sites of Arunachal Pradesh
Arunachal Pradesh currently has no inscribed UNESCO World Heritage property, but it has three sites on India's Tentative List and a rich range of Buddhist, archaeological and indigenous cultural heritage.
Tawang Monastery
Tawang Monastery is one of the most important Buddhist heritage centres of the Eastern Himalaya.
Located high in the mountains of Tawang, the monastery remains a major centre of religious learning, ritual and community life.
Its significance is therefore both architectural and living cultural heritage.
Apatani Cultural Landscape
Ziro Valley demonstrates the heritage value of traditional land management rather than monumental architecture alone.
Apatani settlement patterns, agricultural systems, community institutions and ecological knowledge together create a distinctive living cultural landscape.
Thembang Fortified Village
The fortified Monpa settlement of Thembang preserves a form of vernacular architecture adapted to the Eastern Himalayan environment and reflects historical connections between Arunachal Pradesh, Bhutan and Tibet.
Archaeological Heritage
Sites such as Bhismaknagar and other archaeological remains in eastern Arunachal illustrate the depth and diversity of pre-modern settlement and political history in the state.
Heritage Sites of Assam
Assam currently has the largest concentration of UNESCO World Heritage properties in Northeast India, with Kaziranga, Manas and the Charaideo Moidams.
The state also contains an extensive historical landscape associated with Ahom rule, Neo-Vaishnavism, pilgrimage traditions and colonial industrial heritage.
Sivasagar and Rangpur
Sivasagar preserves one of the richest concentrations of Ahom-period architecture.
Important monuments include:
- Rang Ghar – a ceremonial pavilion traditionally associated with royal viewing of games and performances;
- Talatal Ghar – an extensive palace and military complex;
- Kareng Ghar – associated with the Ahom royal complex at Garhgaon;
- Siva Dol and associated temples;
- historic tanks such as Sivasagar, Joysagar and Gaurisagar; and
- bridges, temples and surviving elements of historic road and water systems.
The addition of the Rangpur-Sivasagar Historic Ensemble to India's UNESCO Tentative List in 2026 has increased international attention on this larger Ahom cultural landscape.
Majuli and the Satras
Majuli's heritage is closely associated with the Neo-Vaishnavite movement.
The island's satras preserve traditions of:
- religious theatre;
- music;
- dance;
- manuscripts;
- mask-making;
- painting; and
- community religious practice.
Hajo
Hajo is notable for its overlapping Hindu, Islamic and Buddhist associations and represents the multi-layered religious heritage of the Brahmaputra Valley.
Tezpur and Da-Parbatia
The Tezpur region contains important archaeological remains, including the historic sculptural and architectural heritage associated with Da-Parbatia.
Heritage Sites of Manipur
Manipur currently has no inscribed World Heritage property, but the Keibul Lamjao Conservation Area is on India's Tentative List.
Kangla
Kangla in central Imphal is one of Manipur's most important historical and archaeological places.
For centuries it functioned as a political and sacred centre of the kingdom of Manipur.
The landscape includes:
- former palace areas;
- moats;
- sacred structures;
- archaeological remains; and
- later historical layers associated with British occupation.
Its significance extends far beyond surviving architecture because Kangla remains central to historical memory and Meitei cultural identity.
Shree Shree Govindajee Temple
The historic Govindajee Temple in Imphal represents the strong Vaishnavite traditions that became an important part of Manipur's religious and performing arts heritage.
INA Memorial at Moirang
Moirang occupies an important position in the history of India's independence movement through its association with the Indian National Army.
The INA Memorial preserves photographs, documents and other material connected with that period.
Heritage Sites of Meghalaya
Meghalaya currently has no property inscribed on the UNESCO World Heritage List, but it has one of the strongest collections of active Tentative List properties in Northeast India.
These are the Garo Hills Conservation Area, Jingkieng Jri Living Root Bridge Cultural Landscapes and Meghalayan Age Caves.
Living Root Bridges
Living Root Bridges combine botany, traditional engineering and community knowledge.
Rather than being constructed once and then maintained as inert structures, they remain alive and strengthen as the roots continue to grow.
This makes them a particularly unusual form of living heritage.
Nartiang Monoliths
Nartiang in the Jaintia Hills contains one of the most striking concentrations of monoliths in Northeast India.
The site contains standing stones and horizontal slabs associated with ancestors, rulers, rituals and historical memory.
The monolith tradition demonstrates the importance of megalithic heritage in Khasi-Jaintia society.
Sacred Groves
Traditional sacred groves such as those associated with Mawphlang preserve both biodiversity and cultural practice.
These forests demonstrate how customary beliefs and community institutions can act as long-term conservation systems.
Heritage Sites of Mizoram
Mizoram currently has neither an inscribed UNESCO World Heritage property nor a property on India's current World Heritage Tentative List.
However, the state contains significant archaeological and community heritage.
Vangchhia – Kawtchhuah Ropui
The Vangchhia archaeological landscape in Champhai district is among Mizoram's most important archaeological heritage sites.
The area contains large numbers of carved stones, menhirs, graves and other archaeological features.
Mizoram Tourism identifies the site as the state's first protected archaeological site.
Vangchhia is important because it contributes physical archaeological evidence to the study of past settlement and cultural landscapes in a region where much historical knowledge has traditionally been transmitted orally.
Traditional Village Landscapes
Mizoram's heritage is also strongly expressed through settlement traditions, community institutions, textiles, oral histories, memorial stones and cultural practices rather than through large monumental architecture.
Heritage Sites of Nagaland
Nagaland currently has no inscribed World Heritage property, but the Naga Hill Ophiolite was placed on India's Tentative List in 2025.
Kachari Ruins of Dimapur
The remains of the historic Kachari kingdom at Dimapur constitute one of Nagaland's principal archaeological sites.
Several remains in Dimapur are protected archaeological monuments.
The site represents an important pre-colonial political landscape and adds another dimension to Nagaland's better-known village and indigenous cultural heritage.
Khonoma
Khonoma has strong historical importance and is associated with local resistance, village institutions and later community-led conservation initiatives.
The village demonstrates how historical heritage, indigenous architecture, terraced agriculture and environmental stewardship can occur within the same cultural landscape.
Naga Hill Ophiolite
The Naga Hill Ophiolite represents a newer understanding of heritage in which geological formations themselves can possess international scientific value.
Heritage Sites of Sikkim
Sikkim contains Northeast India's only mixed UNESCO World Heritage property: Khangchendzonga National Park.
Its wider cultural landscape also includes Buddhist monasteries, former capitals and sacred natural features.
Rabdentse Ruins
Rabdentse was the second capital of the former kingdom of Sikkim.
The surviving ruins preserve the archaeological remains of the former royal centre and are protected by the Archaeological Survey of India.
Pemayangtse Monastery
Pemayangtse Monastery is one of Sikkim's important historic monasteries and forms part of the state's Buddhist cultural landscape.
Yuksom and Norbugang
Yuksom occupies a central place in Sikkim's political and religious history as the landscape associated with the establishment of the early Sikkimese monarchy.
Sacred Natural Heritage
In Sikkim, sacred heritage frequently combines natural and cultural elements.
Mountains, lakes, caves and forests may carry religious meaning, which helps explain the mixed World Heritage character of Khangchendzonga National Park.
Heritage Sites of Tripura
Tripura currently has no inscribed UNESCO World Heritage property, but Unakoti is included on India's Tentative List.
Unakoti
Unakoti is one of the most visually distinctive archaeological and religious landscapes of Northeast India.
Its enormous rock-cut images, smaller sculptures, streams and forested hill setting create a site where archaeology, religion and natural landscape are inseparable.
Neermahal
Neermahal is a former royal summer palace situated within Rudrasagar Lake.
Completed during the twentieth century under the Manikya rulers, the palace combines elements of Hindu and Islamic architectural design.
The integration of palace architecture with a lake landscape makes Neermahal one of Northeast India's most recognizable built heritage sites.
Ujjayanta Palace
Ujjayanta Palace in Agartala forms another major component of Tripura's royal heritage and today houses the Tripura State Museum.
Pilak and Baxanagar
The archaeological landscapes of Pilak and Baxanagar preserve important evidence of historical religious and cultural exchange.
Tripura's tourism policy identifies these areas, together with Unakoti and Udaipur, as important heritage-tourism zones.

Why Heritage Conservation Matters in Northeast India
Preserving Historical Memory
Heritage sites preserve physical evidence of kingdoms, communities, migration, religion, conflict and cultural exchange.
Protecting Indigenous Knowledge
Living heritage landscapes such as the Apatani valley and Meghalaya's living root bridges depend on skills and knowledge transmitted across generations.
Biodiversity Conservation
Natural World Heritage properties such as Kaziranga, Manas and Khangchendzonga protect ecosystems containing rare and threatened species.
Supporting Local Identity
Sites such as Charaideo, Kangla, Khangchendzonga, Nartiang and Unakoti carry meanings that extend far beyond tourism.
They form part of community identity, historical memory and sacred geography.
Sustainable Tourism
Well-managed heritage tourism can support guides, artisans, transport providers, homestays and local businesses.
However, increased visitor numbers must be balanced with conservation.
Major Threats to Heritage Sites of Northeast India
- Heavy rainfall and erosion: damage earthen structures, archaeological sites and exposed rock surfaces.
- Flooding and riverbank erosion: particularly important in Majuli and Brahmaputra Valley heritage landscapes.
- Vegetation growth: roots and moisture may damage masonry and archaeological remains.
- Earthquakes and landslides: significant concerns in the seismically active Eastern Himalaya and Indo-Myanmar ranges.
- Unplanned construction: may alter the visual setting and integrity of historic landscapes.
- Tourism pressure: unmanaged crowds, waste and physical contact may degrade fragile sites.
- Loss of traditional knowledge: threatens living cultural landscapes even when physical structures survive.
- Climate change: may influence forests, glaciers, rainfall, erosion and extreme weather affecting natural and cultural sites.
Heritage Conservation and Sustainable Tourism
The heritage of Northeast India cannot be protected through monument restoration alone.
Many important places are living landscapes where communities continue to farm, worship, weave, perform rituals, manage forests or maintain traditional structures.
Effective conservation therefore requires:
- scientific documentation;
- archaeological research;
- protection of buffer zones;
- community participation;
- visitor management;
- heritage-sensitive infrastructure;
- protection of traditional skills;
- landscape-level ecological conservation;
- disaster-risk planning; and
- accurate interpretation for visitors.
In places such as Majuli, Khangchendzonga, Living Root Bridge villages and the Apatani landscape, separating cultural heritage from the surrounding environment would remove much of the significance of the site itself.

No. The Apatani Cultural Landscape in Arunachal Pradesh is currently on India's Tentative List.
Does Nagaland have a UNESCO World Heritage Site?
Nagaland currently has no inscribed World Heritage property. The Naga Hill Ophiolite was added to India's UNESCO Tentative List in 2025.
Does Mizoram have a UNESCO World Heritage Site?
No. Mizoram currently has no inscribed World Heritage property and no property on India's current World Heritage Tentative List. It nevertheless has important archaeological and cultural heritage, including Vangchhia.
What is the difference between a World Heritage Site and a Tentative List site?
A World Heritage Site has already been formally inscribed by the UNESCO World Heritage Committee. A Tentative List property is a site that a country may consider nominating in the future and therefore does not yet have World Heritage status.
Conclusion
The UNESCO World Heritage and heritage sites of Northeast India reveal a region whose history cannot be separated from its geography.
Kaziranga and Manas demonstrate the global importance of Assam's floodplain and foothill ecosystems. Khangchendzonga combines Himalayan biodiversity with the sacred beliefs of Sikkim's communities. The Charaideo Moidams preserve the royal funerary traditions and sacred geography of the Tai-Ahom dynasty.
The UNESCO Tentative List reveals an even wider spectrum of potential heritage—from the agricultural landscape of the Apatanis and the fortified Monpa village of Thembang to the floating ecology of Keibul Lamjao, Meghalaya's living root bridges and caves, Tripura's monumental rock carvings and Nagaland's oceanic-crust geology.
At the same time, places such as Kangla, Nartiang, Vangchhia, Dimapur's Kachari ruins, Rabdentse, Neermahal and the architectural landscape of Sivasagar show that internationally designated sites represent only one part of Northeast India's much larger heritage.
The long-term value of these places depends on protecting not only monuments and wildlife but also landscapes, traditional knowledge, community memory, sacred meanings and ecological processes. Heritage conservation in Northeast India must therefore remain closely linked with community participation and sustainable tourism.
