Located approximately eleven nautical miles south from Bombay and about six nautical miles north west of Alibag, Dist. Raigarh, are the Island Sea Forts of Khanderi and Underi. The two early notices of Khanderi in 1538 of the Portuguese Viceroy Dorn Joao da Castro and 1674 of John Fryer, refer to it as ar uninhabited island.

In August 1679, Shivaji whose naval power had by now considerably increased, occupied the islands ant oversaw the construction of a fortification, wall. The British attempt to claim the islands 'for the Crown' and oust Shivaji failed miserably. The Janjira Siddi followed the British in an attempt to unseat the Marathas but followed suit. All attempts by the British and the Siddi to capture Khanderi - Underi, forts did not fructify till 1750. It was finally ceded to the British in 1818 "as part of the Peshwa territory"

In 1687, the British built a Light House on the Island which still stands. Even today, there is a temple Of Vetal and the Tomb of Daud Pir both of which are worshipped by the local fishermen community.
