Sivasagar Tank, also known as Borpukhuri, is a large man-made tank located in the heart of Sivasagar town. It's a prominent landmark and a popular spot for locals and tourists alike. The tank is surrounded by historical structures like the Shiva Dol, Vishnu Dol, and Devi Dol, creating a serene and picturesque environment. Visitors can enjoy a leisurely walk around the tank, appreciate the architectural beauty of the temples, and experience the calm atmosphere. The tank's vast expanse of water and the surrounding greenery offer a refreshing escape from the bustle of the town. It's a perfect place for photography and relaxation.
The Sivasagar Tank was constructed by the Ahom kings in the 18th century. It was commissioned by Queen Ambika, the wife of King Siva Singha, and completed in 1734. The tank was dug to provide a reliable water source for the growing population of the capital city, Rangpur (present-day Sivasagar). The construction of such a large tank during that era demonstrates the engineering prowess of the Ahom kingdom. The tank has been a significant part of the town's history and has witnessed many historical events. It stands as a testament to the Ahom dynasty's rich cultural heritage.
