Explanation:

The Anangpur Dam, located close to the Anagpur village (also called Arangpur) in Faridabad district of Haryana, India, is 2 kilometres (1.2 mi) away from the more famous Surajkund. This unique Indian hydraulic engineering structure was built during the reign of King Anangpal of the Tomar dynasty in 8th century. It is approachable by road from Delhi from the Delhi - Mathura road. The ruins of the fortifications found in Anangpur village establishes by an inference that it was built by Anangpal as part of the Lal Kot that was developed as the first city of Delhi in the 8th century.
