Salimgarh Fort

Salimgarh Fort was raised in 1546 by Salim Shah Suri, son of Sher Shah Suri, on what was then an island in the Yamuna, during the years when the Sur dynasty had pushed the Mughals out of Delhi. Humayun is said to have camped here for three days before retaking the city in 1555, and he afterwards renamed it Nurghar. Shah Jahan is believed to have stayed here while building the Red Fort and Shahjahanabad.

The site was chosen for its rock base, with the river on one side and the Aravalli ridge on the other forming a natural barrier. Aurangzeb turned it into a prison, and the British kept that use after taking it in 1857. Today it forms part of the Red Fort Complex, which UNESCO listed as a World Heritage Site in 2007.
