Maharashtra’s Sea Forts: Living Legacies of India’s Maritime Power

Stretching along the Arabian Sea, Maharashtra’s coastline is home to some of India’s most remarkable sea forts. Built between the 15th and 18th centuries, these forts once guarded trade routes, repelled invaders, and showcased the naval strength of different dynasties, especially during the Maratha era. Today, Maharashtra’s Sea Forts stand as reminders of the state’s rich history and ingenious military engineering.
Sindhudurg Fort

Located off Malvan in Sindhudurg district, Sindhudurg Fort was built by Chhatrapati Shivaji Maharaj in 1664. Spread across 48 acres, the fort has 42 bastions, a 3-km-long wall, and even secret escape routes. A unique temple dedicated to Shivaji Maharaj adds to its significance. Accessible by boat from Malvan jetty, the fort remains closed during the monsoon months.
Murud-Janjira Fort

Standing strong in the Arabian Sea off the Raigad coast, Murud-Janjira is one of the few forts never conquered despite repeated sieges by the Portuguese, British, and Marathas. First built by local fishermen in the 15th century and later fortified by Malik Ambar, the fort still has 26 intact bastions, freshwater lakes, and storages that hint at its self-sustaining design. Visitors can reach it via ferry from Rajapuri village.
Vijaydurg Fort

Near Devgad in Sindhudurg district lies Vijaydurg, first built in the 12th century and later strengthened by Shivaji Maharaj. Surrounded by the sea on three sides, the fort once had a naval dockyard used to build Maratha warships. It is easily accessible by road from Devgad and offers sweeping views of the Konkan coast.
Khanderi and Underi Forts

Close to Alibaug, these twin forts often saw clashes between the Marathas and the Siddis. Khanderi, developed by Shivaji Maharaj in 1679, has a British-built lighthouse still in use. Underi, constructed by the Siddis, served as a defensive post. Boats from Thal village provide access, though services depend on the tides.
Kolaba Fort

Just off the Alibaug coast, Kolaba Fort was a key naval base for Shivaji Maharaj. Built in 1680 and completed by his son Sambhaji, it features wells, temples, and cannons of both English and Portuguese origin. During low tide, visitors can walk to the fort from Alibaug beach, making it one of the rare tidal forts in India.
From Sindhudurg’s sprawling walls to the unbeaten strength of Janjira, Maharashtra’s Sea Forts are more than stone structures. They are living legacies that tell the story of Maharashtra’s maritime glory, inviting travellers to step back in time along the state’s stunning coastline.
