Ana Sagar Lake, sprawling over an area of 13 km, is an artificial lake which was built by Anaji Chauhan, the grandfather of Prithvi Raj Chauhan. The catchments at the lake were built with the help of the local people between 1135 and 1150 A.D.
The Daulat Bagh gardens were built by Emperor Jahangir in the area surrounding the lake. The lake has an island and is surrounded by beautiful parks and marble pavilions. Boats and water scooters are available from the eastern side of the Daulat Bagh gardens for tourists to reach the island.
Additional constructions were also made by the Mughals to enhance the beauty of the lake. The Circuit House, which served as residence to the British is located on a high hill near the lake.
