Built by Anaji during 1135-1150 AD, this lake is located towards the north of Ajmer city. Later the Mughal Emperors made additional constructions to beautify the lake. The 'Baradari', Shah Jahan built a marble pavilion. This lovely lake built by King Anaji, the grandfather of Prithvi Raj Chauhan is at a picturesque site located to the north of Ajmer. Next to the lake are the Daulat Bagh Gardens, set up by emperor Jehangir. Shah Jahan added the Baradari (marble pavilion) to the lake. Shah Jahan built the marble pavilion now called the Baradari, while Emperor Jehangir laid the beautiful Daulat Bagh gardens, where people still go in plenty to walk and enjoy the greenery

This artificial lake was created in the 12th century by damming the river Luni. On it's bank is the fine park, Dault Bagh, containing a series of marble pavilions. It's popular for an evening stroll. The lake tends to dry up if the monsoon is poor, so the cities water supply is taken from Foy Sagar, 3 kms. further up the valley. There are good views from the hill beside the Dault Bagh.
