Located in the northeastern state of Assam in India, Sivasagar, formerly known as 'Rangpur,' stands as a testament to the rich cultural heritage and historical grandeur of the Ahom Dynasty that ruled for nearly 600 years. The town's name, 'Sivasagar,' translates to 'the ocean of Lord Shiva' and is notably marked by the Sivasagar Sagar, a large man-made tank ordered by the Ahom queen. Surrounding the tank, significant monuments like the Sivadol, Vishnudol, and Devidol temples reflect the splendor of Ahom architecture. The Sivasagar Tank itself was constructed by binding the waters of river Dikhow, and it remains filled throughout the year. Apart from its religious significance, Sivasagar is known for architectural marvels like the Talatal Ghar and Rang Ghar, which offer insights into the Ahom Kingdom's past. Rang Ghar, often referred to as the Colosseum of the East, was used as a sports-pavilion by Ahom kings. The area also represents the town's strategic importance in tea and oil industries, contributing significantly to Assam's economy. With a blend of history, culture, and scenic beauty, Sivasagar is a hub for researchers and tourists alike.
