Kohanduvale

Kohanduvale is a tanks located in Sivasagar district of the Indian state of Assam. It is believed to be built during the Ahom dynasty, which ruled Assam from the 13th to the 19th century. The tank is also known as the "Water Palace" and is said to have been constructed in the late 16th century during the reign of King Prataap Singha.

Kohanduvale is an earthen tank that measures approximately 1.5 kilometers in length and 500 meters in width. It was built using bricks and is surrounded by earthen walls, with a small gateway serving as the entry point. The tank's water source is a natural spring, which is believed to be the reason behind its construction.

In the early 19th century, the tank was extensively used as a major source of water supply for the nearby village and also as a source of water for irrigation. After the Ahom dynasty's decline, the tank fell into disrepair, and it gradually ceased to be used.

Kohanduvale is considered an important historical monument in the state of Assam and has been declared a protected monument by the Archaeological Survey of India. Despite its rich historical significance, the tank remains in a relatively poor state of preservation and is in need of conservation efforts to restore it to its former glory.

Researchers and historians have identified Kohanduvale as an important example of ancient Indian engineering and water management techniques, particularly during the Ahom era. The tank's construction and layout provide valuable insights into the cultural and architectural practices of the time.
