Rajon Ki Baoli is a famous stepwell near Adham Khan's Tomb in Mehrauli. This magnificent three-storeyed stepwell is believed to have been built by Daulat Khan during the reign of Sikandar Lodi in 1516.[1] The baoli was used by masons for some time. Hence, it got its name as Rajon Ki Baoli.
The baoli is one of the highlights of Mehrauli Archaeological Park and a favourite with every visitor. Perhaps it is to do with manner in which it is revealed to the eye: the entire structure is subterranean, so as one approaches the entrance, one can only see the top-most storey. And each level of the baoli slowly reveals itself to the visitor as one walks towards its steps. The baoli-complex has a 12-pillared tomb and a mosque with some pretty plaster decoration on it.
