Located in the national capital city of Delhi, the Tughlaqabad Fort was built in 1321, by Ghiyas-ud-din Tughlaq who founded the Tughlaq dynasty. The construction of the fort was intended to keep the marauding Mongolian raiders at bay and was known as the 3rd historic kingdom of Delhi. The fort is also connected to the tomb of Ghiyas ud-din Tughlaq, which sits at a scenic location beside a highly ornamental causeway.
