# Assam's 600-year-old Ahom capital edges closer to a UNESCO honour > India has formally nominated the Rangpur-Sivasagar Ensemble, the surviving seat of Assam's six-century Ahom dynasty, for a place on UNESCO's World Heritage list, Chief Minister Himanta Biswa Sarma said, calling it a follow-up to the 2024 listing of the Charaideo Moidams. **Type:** article · **Category:** Assam · **Published:** 2026-09-05 · **Source:** TrendKia **Canonical:** https://trendkia.com/en/assam/chhaha-sadi-raja-karane-vale-ahom-vnsha-ki-rajadhani-rangpur-sivasagar-aba-unesco-ki-dahalija-para-28077 · **Language:** English **Tags:** UNESCO World Heritage, Ahom dynasty, Assam heritage, Rangpur-Sivasagar Ensemble, Rang Ghar, Charaideo Moidams, Himanta Biswa Sarma, Sivasagar The remains of the Ahom dynasty's six-century-long capital in Assam are now in the running for global recognition, with India formally putting the Rangpur-Sivasagar Ensemble forward for inclusion on UNESCO's World Heritage list. Chief Minister Himanta Biswa Sarma shared the update, framing it as a fresh push to showcase the state's Ahom-era legacy on the world stage. ## A capital that endured six centuries The Ahom dynasty took control of Assam in 1228 and went on to rule the Brahmaputra Valley without interruption until 1826, an unusually long and stable reign for the region. The Rangpur-Sivasagar Ensemble gathers together the surviving physical evidence of that long rule, spread across the historic capital area of Sivasagar. The complex includes temples, royal palaces, expansive water tanks and engineering works that, taken together, are meant to demonstrate the scale of the dynasty's architectural and technological reach. > ## Rang Ghar, Asia's oldest amphitheatre Among the structures included in the nomination, the Rang Ghar stands out as the best known. Sarma has called it Asia's oldest surviving amphitheatre, and it remains one of the clearest visual symbols of Ahom-era engineering still standing in Sivasagar today. ## How the nomination was filed India's permanent mission to UNESCO formally submitted the Rangpur-Sivasagar Ensemble on 19.06.2026, seeking its inclusion under UNESCO criteria (iii) and (iv), the categories that assess a site's testimony to a cultural tradition and its standing as an outstanding architectural ensemble. Sarma made the submission public through a social media post put out on Friday night, confirming that the paperwork had already been filed with the world body. ## Building on the Charaideo Moidams listing This is not Assam's first attempt at securing UNESCO recognition for Ahom heritage. The Charaideo Moidams, the dynasty's royal burial mounds, were inscribed on the UNESCO World Heritage list in 2024, and Sarma described the new nomination as a natural continuation of that success. He said, "Together, the two sites complete the Ahom story: where the dynasty rests, and where it ruled," linking the burial ground at Charaideo with the seat of power at Sivasagar. ## Credit to the Centre Sarma also thanked Prime Minister Narendra Modi, crediting him with what he called an "unprecedented push" to win wider international recognition for Assam's historical and cultural heritage. The chief minister's post framed the nomination as part of a broader, sustained effort by both the state and the central government to place Assam's Ahom-era sites alongside other globally recognised heritage locations. ## What this means for you If UNESCO approves the listing, it would give Assam a second Ahom-era World Heritage Site and likely reshape how the region is marketed to travellers and researchers. - **Across India:** A successful listing adds another entry to the country's UNESCO tally, strengthening the case for future nominations from other states. It also gives Indian researchers and conservation bodies a fresh, high-profile case study in restoring large, multi-structure heritage complexes. - **In Sivasagar, Assam:** Recognition would likely draw more domestic and international tourists to the Rang Ghar and the surrounding Sivasagar complex. That, in turn, could bring more hotel, guide and local business activity to a town that currently sees comparatively modest tourist footfall. - **For heritage upkeep:** A UNESCO tag typically comes with tighter conservation obligations and closer monitoring. Local authorities would need to maintain the site to international standards, which can mean added funding and restrictions on nearby construction. - **For the state's cultural profile:** Alongside the 2024 Charaideo Moidams listing, a second Ahom site would let Assam market a combined heritage circuit, potentially packaging both sites together in tourism promotion. ## Questions & Answers ### 1.
