Spread over a vast area of about 9 acres, the Padmadurg Fort is also known as the Kasa fort which is regarded as one among the major sea forts in Raigad district of Maharashtra, India. A monument of great historical importance, this famous fort is constructed by the great Marathas in order to conquer the Janjira Fort which lies nearby.
The fort commemorates the repeated failure attempts of the mighty Marathas regime against the tiny Siddis. It is believed to have spilt in to three by the ravage of time and now it is not accessible to the public. Ruins of this great fort can be seen from the seashore.
