Bhadra Fort is a citadel in the old city of Ahmedabad. Ahmad Shah, Sultan of Gujarat, commissioned the building during his reign (1411-1442/813-846 AH) as part of a larger urban foundation including a mosque, public square, monumental gate, and processional way.
The fortress is roughly square in form and its western side along the river follows the course of the city walls. It has a number of gates, the most monumental of which opens from its east side onto what was once the public square (called Maydan-i Shah). On the wall between the two towers behind this gate, a clock was installed in the mid 19th century.
