Delhi's Agrasen ki Baoli is a gorgeous step-well constructed with such precision and intricate craftsmanship that you will find yourself in a symmetrical heaven. Many recognise it today because of the Indian film PK, where a major scene was shot on its steps. It is 15 m wide and 60 m deep, sitting right near Connaught Place. The Baoli is credited to the Agarwal community from Gujarat or Rajasthan, who constructed it in 14th Century CE and is on most tourist circuits.
