Agrasen ki Baoli (also known as Ugrasen ki Baodi), designated a protected monument by the Archaeological Survey of India (ASI) under the Ancient Monuments and Archaeological Sites and Remains Act of 1958, is a 60-meter long and 15-meter wide historical step well on Hailey Road, near Connaught Place, Jantar Mantar in New Delhi, India. Although there are no known historical records to prove who built Agrasen ki Baoli, it is believed that it was originally built by the legendary king Agrasen, and the present architecture hints at it being rebuilt in the 14th century during the Tughlag period of Delhi Sultanate. The Baoli is open daily from 9 AM to 5:30 PM.
This Baoli, with 108 steps, is among a few of its kind in Delhi. The visible parts of this historical step well consist of three levels. Each level is lined with arched niches on both sides. From an architectural perspective, this step well was probably rebuilt during the Tughlaq period.
