Hi Chanchal.. I was glad to read the history you have added. It is indeed a nice piece of information But I think I can add some more to your story.
Sher Shah Suri and his successor could not complete the city, and when Humayun defeated Sher Shah's son to take back his city, he did not deal with Dilli Sher shahi as the latter had done with Dinpanah. In fact the Mughal emperor very handsomely completed the city and even used several of the buildings like the Sher Mandal, a rather pretty two-storeyed octagonal building. Humayun used this as his library and, then tripped to his death from its steps.
Actually whenever we went for site like this we too a guide who gave the details of the place. So I thought of sharing it with you..
