Kolaba Fort – Alibaug

Kolaba fort alibaug (sometimes Kulaba Fort or Alibag Fort) is an old military fortification in India. It is situated in the sea at a distance of 1–2 km from the shores of Alibag, 35 km south of Mumbai, in the Konkan region of Maharashtra, India. It is a popular tourist destination and a protected monument.
The average height of the fort walls is 25 feet. It has two main entrances, one on the sea side and the other towards Alibag. An interesting feature of this fort is that it has freshwater wells in its premises even though it is a seaside fort. In the monsoons, the fort can be reached by wading through waist-deep water at low tide. However, at high tide, boats must be used to reach it. The Siddhivinayak temple inside the fort was built by Raghoji Angre in 1759.
