Agrasen Ki Baoli, central Delhi’s oldest monument, remains one the best preserved baolis of Delhi. It is located in the narrow Hailey Lane, off Hailey Road, near Connaught Place, New Delhi. Baoli (also called bawdi in Hindi, barav in Marathi, vaav in Gujarati, kalyani or pushkarni in Kannada) is an elaborate well with steps leading down to the source of water. In fact a baoli is much more than a stepwell. It is a staircase-well divided into multiple levels with elaborate architecture, intricate design and in some cases rooms for users.
