Ingeniously constructed by the Shilahar dynasty, Vijaydurg or Viziadurg is the oldest fort on the Sindhudurg coast. Originally known as the ‘Gheria Fort’, after the name of the adjoining village named ‘Girye’, the fort was renamed as “Vijay Durg” by the legendary Maratha leader Shivaji when he captured it from Adil Shah of Bijapur in 1653. Vijaydurg Fort was previously surrounded by the sea from all sides, and thus, it was turned into a naval fortress. However, with time, the fort’s eastern trench was reclaimed and a road was constructed. So now, the fort is bounded by the Arabian Sea on three sides only. Shivaji enhanced the security of the fort by erecting three walls on its eastern side. Each of these walls was 36 meters high. There were also 20 bastions.
