Khanderi is located 5 km off the coast of
Maharashtra (off Thal, Kihim) and 20 km south of
Mumbai. Khanderi, along with its sister fort
Underi (Jaidurg) formed the major fortification along the Maharashtra coast, the former falling under Shivaji Maharaj's control and the latter under his opponents, the Siddis. The island consists of two high hills, one facing north and the other facing south. Initially, the islands of Underi and Khanderi were uninhabited. It contained two wells to supply water to the forces within, and a temple of Sri Betal. The fort is a restricted area, which falls under the jurisdiction of the
Indian Navy. Additionally, the fort has a few old metal canons, the tomb of Daud Pir, a local saint and a musical stone that emits metallic musical notes when struck. There is a one secret way for going on the Kulaba fort of Alibag. ==History==
