This old Portuguese fort stands on the beach south of Candolim, at the shore of the Mandovi River.

Whereas the upper part has a moat, underground water storage chamber, gunpowder room, lighthouse, and bastions, it also has a secret escape passage to use during time of war and emergency.

Built on the mouth of Mandovi River, it was strategically located and was the chief defense of Portuguese against the Dutch.

There was a large bell on the lighthouse which was found in the ruins of Saint Augustine monastery in Old Goa.

The redevelopment cost approximately Rs 22 crore under the Centre's Swadesh Darshan Scheme.

This museum has two particular cells dedicated to liberation fighters T B Cunha and Ram Manohar Lohia, where they were imprisoned under the Portuguese regime.
