This is an old step well water reservoir and a historical and architectural delight. The baoli is bang in the middle of central Delhi and on a good day it can prove to be quite the picnic spot! The further you step in the further away you feel from the craziness of the city!
Pro tip: Don’t forget to take your camera and don’t forget to read up about it. There are many legends about the place- for all you know you might find it’s haunted!
