The Hari Parbat or the Mughal Fort, located on the banks of the world renowned Dal Lake, has two gates known as Kathi Darwaza and Sangin Darwaza. The Kathi Darwaza, assumed to be the main entrance of the Hari Parbat Fort, is a very simple structure with a domed chamber in the center and two recesses in the sides.
Kathi Darwaza has some Persian commemorative inscriptions in the walls and ceilings. These inscriptions point light to the Persian beliefs and culture. The beautiful external decorations include arched and rectangular panels and two good-looking medallions, on the spandrels of the simple arch.
