Purana Qila (Old Fort):
the recent excavations near this fort, archaeological evidences such as
pottery have been found which throws a new light on the existence of the
city of Indraprastha at this place in Delhi, as mentioned in the great
epic of Mahabharata. Sher Shah Suri built the fort and completed it in
1545. However, he soon lost it to the Mughal emperor Humayun, who made
good use of the octagonal red sandstone tower known as 'Sher Mandal' as
his library and observatory. It is rumored that Humayun slipped from the
second storey steps and met his death here. There is a dainty small lake
in its premises, where one can enjoy boat rides during summers.
