Kanakdurg Fort

Kanakdurg Fort is a coastal headland fort located at Harnai port in Ratnagiri district, Maharashtra. Built primarily by Kanhoji Angre, it served as a strategic land-based lookout and harbor defense for the nearby sea fort of Suvarnadurg. The fort covers approximately 0.25 hectares and features a functional lighthouse, nine water tanks, and dilapidated bastions. It offers views of the Arabian Sea, Suvarnadurg island, and the active Harnai fish market below.

Visitors can explore the ruins of a small Maratha-era coastal fort situated on a headland projecting into the Arabian Sea. Access is via a flight of steps leading to an oval-shaped enclosure containing nine aligned water tanks and two ruined bastions. A functional lighthouse and weather department office occupy the southern elevated section. The site provides vantage points for viewing the adjacent Suvarnadurg sea fort, Harnai port's fishing activities, and sunsets over the ocean. The terrain is uneven with rocky edges near the sea.

Kanakdurg Fort was constructed primarily by Kanhoji Angre, Admiral of the Maratha Navy, as part of a defensive network protecting the Suvarnadurg sea fort from land-based attacks. Along with Fattegad and Gova forts, it formed a strategic surveillance system guarding the Harnai harbor and maritime routes during the Maratha era. The fort later came under British control after the decline of Maratha naval power in the early 19th century.

The fort remains a visible landmark of Maratha maritime heritage along the Konkan coast. Its proximity to the active Harnai fish market connects historical defense structures with ongoing traditional fishing livelihoods. Locals and tourists frequently visit in the evenings to observe the interplay between historic architecture and contemporary coastal life.
