The original Fort William was named after King William III of England.
The current, larger star-shaped fort was constructed by Robert Clive after the Battle of Plassey in 1757.
The fort's construction costs were largely defrayed by the wealth acquired after the defeat of the Nawab of Bengal.
The expansive Maidan surrounding the fort was cleared of trees to ensure an unobstructed field of fire for the fort's cannons.
The fort's design includes a complex system of dry moats and ravelins typical of Vauban-style fortification.
The Eastern Command of the Indian Army, which administers the fort, is one of the oldest commands in the country.
Fort William is an 18th-century fortress located on the eastern banks of the Hooghly River in Kolkata. Built by the British East India Company, it served as a strategic military base and remains an active garrison under the Indian Army's Eastern Command today. The fort consists of an octagonal structure featuring massive bastions and a deep moat. It is situated within the expansive Maidan park area of central Kolkata. Visitors can view the external architecture, which reflects 18th-century European military engineering. The site functions as a restricted military zone, and public access is strictly regulated.
The perimeter of the Maidan provides the best vantage point for capturing the exterior walls and the scale of the fortification.
