One of the best preserved forts of the Marathas, Sindhudurg fort has zigzag rampart with 42 bastions. Apart from the huge stones, the building material involved 2000 khandis (72,576 kg) of iron erecting the massive curtain wall and bastions. A notable feature is that the foundation stones were laid down firmly with 5 khandis (181.5 kg) of molten lead.
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.
