Fort George was an extension to the fortified walls of Mumbai built in 1769; it was situated in the present Fort area, to the east on the site of the former Dongri Fort. The hill on which the Dongri fort stood was razed, and in its place Fort George was built. In 1862, the fort was demolished.
The fort was 1 mile (1.6 km) long and about a third of a mile in breadth (500 m). Its length was from NNE to SSW, and it was named in honour of George III of the United Kingdom.
