The lake was constructed by damning the Luni River tributaries to store water, making it one of the oldest artificial lakes in India.
The lake area also includes marble pavilions and gardens built by Mughal Emperor Shah Jahan and Jahangir.
Ana Sagar is spread over 13 square kilometers and is a key tourist attraction in Ajmer.
It serves as an important source of water storage and supports local biodiversity.
The lake has a Daulat Bagh Garden nearby, developed during the Mughal period.
The Bhartrihari Temple and Ajmer Sharif Dargah are located close to Ana Sagar.
Despite being artificial, it is now integrated into the local ecosystem.
The lake is also a seasonal habitat for migratory birds.
