Vijaydurg Fort The ASI presents a comprehensive view of the formidable Vijaydurg Fort, surrounded by water on three sides and strategically located on the southern bank of the Vaghotan River near the Kharepatan Creek, which historically functioned as a port. Built of laterite stone, the fort features powerful triple-line fortifications reinforced by 27 bastions, including three multi-storied bastions. Envisioned by Chhatrapati Shivaji Maharaj to extend Maratha influence beyond the Sahyadris and the Deccan plateau, Vijaydurg emerged as a key naval base.
