Revdanda fort was a beach facing fort built in 1558 by a Portuguese captain Soj to watch over their trading interests. It is located in lower Chaul, which one comes across on the Alibaug-Murud road (17kms away from Alibaug). During the Portuguese times it was called Santa Maria de Castelo, but the locals called it Revdanda after Revati the spouse of the Yadava king Balrama.

The Portuguese stoically defended this fort against many invasions namely in 1570-71 and in 1594. It was captured by the marathas (by the Angres, during the time of Nanasaheb Peshwe) in 1740 (Note.an earlier attempt in 1683, during the time of Ch.Sambhajiraje had failed). In 1

06 it was ceded to the East India company and remained in brief control of the Angres in 1817.

Revdanda-Chaul (Chenwal in Konkani language) has a history of 2000 years. Chaul (Simul,Champavati were some of its old names) was ruled in the medieval times by kings like Bhoja (12th cen) and Bimbadev (13th cen).Chaul came under Tughluq in the 14th century , the Bahamani sultans in the 15th century, Nizamshahi in 16th century, Portuguese in the 16/17th century (1505 onwards. In 1508, an combined army of Egyptian Mamluks and Gujrat sultanate defeated the Portuguese. The first Portuguese settlements started in 1521 with the permission of Nizamshah), the Marathas in the 18th century and the British in the 19th century.
