On western side of Mumbai, there is a famous beach of Kelve. From this village Bhavangad fort is 3 km away. During Vasai campaign the Marathas built this fort to put a check on Portuguese.
In 1526, Portuguese started building Vasai fort. To control the entire region they created chain of forts in Shirgao, Mahim and Kelve. They forced locals to change their religion. When the Peshwas got a hint of this, they started a campaign against Portuguese in 1737. Under the leadership of the great Chimaji Appa, warriors like Gangaji Naik, Shankaraji Phadke and Baji Rethekar fought against the Portuguese.
The fort was built during the time of Vasai campaign, right in the middle of the monsoons. 2000 workers were used for the same.
