Presently the Mehrauli- Badarpur Road, it is a ruined fort that was once a dream of Emperor Ghiyas-ud-din- Tughlaq. He was the founder of the Tughlaq Dynasty and is known to have been a dictator by nature. It was his dream to set up a magnificent fort for himself but fate had something else in store. The fort was made for sure but the emperor could not enjoy his stay there. An old story says that when the fort was being made, the emperor had ordered all masons and workers to work only on this project and nowhere else. This forceful attitude was not liked by Nizamuddin Auliya, a Sufi saint of that time. He cursed the emperor that either the fort will remain unbuilt or will be inhabited by Gujjars. This is absolutely what happened as the Gujjars later took ownership of the fort and started living in that area. Another curse that is said to be the reason of death of the Emperor was when the saint said Dilli Bohut Door. At this time Tughlaq was elsewhere and while returning, his son conspired a murder of his father. The mausoleum of the Emperor is also built here now.
