The Worli Fort is an ancient British fort in Worli area in Bombay, India. The fort, often mistakenly referred to as being built by the Portuguese, was actually built by the British around 1675. The fort, built on the Worli hill, overlooked the Mahim Bay at a time the city was made up of just seven islands. It was used as a lookout for enemy ships and pirates.

The fort is completely in ruins today and a slum has enveloped the edifice. A bell tower peeps out of the ruins and the ramparts are used to dry clothes. Historians have often called for the protection of the area but their efforts have fallen on deaf ears.
