Vellore Fort was built by Chinna Bommi Reddy and Thimma Reddy Nayak, subordinate chieftains under Sadasiva Raya of the Vijayanagara Empire in the year of 1566 AD.
It is mentioned that "there is no such fort on the face of earth like the one in Vellore. It had a deep wet ditch (moat) where once 10,000 crocodiles swarmed, waiting to grab every intruder into this impregnable fort. It has huge double walls with bastions projecting irregularly, where two carts can be driven abreast". The fort was constructed in granite from the nearby quarries in Arcot and Chittor districts. It spreads over an area of 133 acres.

The fort is surrounded by a moat which was once used as an additional line of defence in the case of an invasion. It includes an escape tunnel leading to Virinjipuram about 12 km (7.5 mi) away, which could be used by the king and other royals in the event of an attack, later disputed by researchers of the ASI who found no evidence of existence of such passage. The fort is considered to be among the best of military architecture in Southern India and is known for its grand ramparts, wide moat and robust masonry.
