Vijaydurg (sometimes written as Viziadurg), the oldest fort on the Sindhudurg coast, was constructed during the regime of Raja Bhoja II of the Shilahar dynasty (construction period 1193-1205) and restructured by Chhatrapati Shivaji Maharaj. Vijaydurg Fort was called the "Eastern Gibraltar", as it was virtually impregnable. Its locational advantages include the 40 km long Waghotan/Kharepatan creek. Large vessels cannot enter the shallow water of this creek. Also, Maratha warships could be anchored in this creek and yet remain invisible from the sea. It is a protected monument.
