Sindhudurg-Fort

Sindhudurg Fort is a fort that occupies an islet in the Arabian Sea, just off the coast of Maharashtra in Western India. The fortress lies on the shore of Malvan town of Sindhudurg District in the Konkan region of Maharashtra, 450 kilometres (280 mi) south of Mumbai.It is a protected monument.This fort was constructed by Shri Chhatrapati Shivaji Maharaj, the Chhatrapati of the Maratha Empire.The construction was done under the supervision of Hiroji Indulkar, in the year 1656.

Over 4000 mounds of iron were used in the casting and foundation stones were firmly laid down. Construction started on 25 November 1664. Built over a period of three years (1664–67), the sea fort is spread over 48 acres (190,000 m2) with a two-mile (3 km) long rampart, and walls that are 30 feet (9.1 m) high and 12 feet (3.7 m) thick. The massive walls were designed to serve as a deterrent to approaching enemies and to the waves and tides of the Arabian Sea. The main entrance is concealed in such a way that no one can pinpoint it from outside.At a time when travelling by sea was banned by scriptures, this construction on an island represents the revolutionary mindset of its engineer. A remain of an iron mould can be seen on the fort.
