Located just 2 km away from Ratnagiri, Ratnadurg is a famous tourist attraction. Because of the Bhagwati temple inside the fort, it is also called as Bhagwati fort. The fort is built in the Bahamani period. In 1670, Shivaji Maharaj won the fort from Adil Shaha of Bijapur. After Shivaji Maharaj, the East India Company took over the fort & the British ruled it till 1947. It is a moderate size fort with an area of more than 120acres. It is considered one of the strong forts on the western shore. Its strategic position is best to keep watch on the Arabian Sea and the Ratnagiri harbor
