India’s Permanent Delegation to UNESCO formally submitted the nomination of the historic ensemble on this date under UNESCO World Heritage criteria (iii) and (iv) . The site was added to the Tentative List , paving the way for its future consideration for full World Heritage status . The ensemble reflects the architectural, cultural, and engineering achievements of the Ahom kingdom , which ruled the Brahmaputra Valley for nearly six centuries . Additional Information The Rangpur-Sivasagar Ensemble includes several remnants of the Ahom era, such as Rang Ghar , Talatal Ghar , historic temples, roads, bridges, and large tanks like Joysagar , Gaurisagar , and Sivasagar . The Ahom kingdom is a significant part of Assam's history, having maintained control over the region for hundreds of years.
