On the main Press Enclave Road near Khirki Village, their is a interesting 14th century waterworks known as Satpula (`Seven Bridges’).
Satpula, a weir about 65m high, was built by Mohammad bin Tughlaq in 1323. When Mohammad bin Tughlaq ascended the throne of Delhi, he built a new city for himself called Jahanpanah.
Satpula or the weir is an impressive example of the waterworks projects carried out under the Tughlaq dynasty.
Satpula consisted of a solidly built stone dam with seven wooden sluices to regulate the flow of water from an artificial lake (filled with rainwater) to the fields outside the city.
Satpula itself, with its solid walls and seven arched openings, has recently been restored by the Archaeological Survey of India. You can climb up onto the wide parapet and see the structure for yourself, but don’t expect anyone to guide you around—there isn’t likely to be anyone there. Satpula can be visited any time, and there isn’t any entry fee.
