Revdanda is a village near Alibaug, Raigad District, Maharashtra. It is the site of the medieval 'Chaul harbor'.

India. It is connected through a coastal highway (Sagari Mahamarg) 17 km (11 mi) away from Alibag, 125 km (78 mi) away from Mumbai, 37 km away from Roha and 33 km away from Murud.

Until a few years ago the coastal road that goes south from Alibag used to terminate at Revdanda where it encountered the Kundalika creek. A bridge now spans the creek and the whole stretch southward of Revdanda up to Murud-Janjira has now become accessible. Part of the town is situated within the premises of Revdanda fort, an old Portuguese fort.

The history of Revdanda and the surrounding villages are quite similar to Chaul, due to their close proximity to the town.

In 1490 the area fell under the Ahmadnagar Sultanate.

In 1505, Portuguese commander Dom Lourenço de Almeida defeated the Muslims and conquered the area around Chaul. In 1508, Venetian mercenaries along with the Mamluk navy had allied with Sultanate of Gujarat and defeated the Portuguese in the Battle of Chaul. The first Portuguese settlement at Chaul took place in 1521 with the construction of the first fort on the south bank of the Kundalika River. In October 1531, the Portuguese erected a new square stone fortress, named Santa Maria do Castello, which contained a church and dwellings for 120 men. A village developed around the fortress, which is now called Revdanda. A 1558 treaty precluded fortifying the town.

The Marathas led constant raids against their neighbors, for more land and wealth. Chaul and Revdanda fell to the Marathas during the Battle of Bassein. After the successful campaign by the Marathas, the tower bells from the local churches had been taken as victory symbols and came to be installed in temples. They also gave out parcels of land to their subjects as well as plundered the churches and houses of the native people.

Revdanda became a British territory after they successfully defeated the Marathas in 1818, and took control of the confederacy.

The Fort of Santa Maria do Castello is one of two 16th century fortresses built by the Portuguese, in the area around Tschoul - The other being Korlai Fort.

It is where St. Francis Xavier delivered one of his early sermons in India. The Church of St. Barbara still exists, but in a run down condition. The church is within the walled fort, on the south side and not far from the main road.
