The fort stands atop a 152m hill and covers an area of 700 acres (2.8 km2). It has a number of gateways and ponds including the Gaumukha kund, which is supplied by perennial underground source of water. Heavily fortified, Chittorgarh was believed to be insurmountable until it was sacked by Alauddin Khalji of the Delhi Sultanate in 1303.
