Severndroog Castle is a castle folly built on Shooter’s Hill in South East London.
It was designed by the architect Richard Jupp to commemorate Commodore Sir William James who died in 1783.
Commodore Sir William James was a Welsh-born British navy commander, known for his successful campaigns against Indian native navies and the destruction of the island fortress of Suvarnadurg (Severndroog) of the Maratha Empire in India.
The castle offers commanding views across London along with the surrounding counties. In 1797 General William Roy used Severndroog Castle for his trigonometric survey linking England and France. It was also used by the Royal Engineers in 1848 for a survey of London.
During WW2, the castle played an important role in the air defence of London. Manned by observers, the elevated position gave a high vantage point to spot for enemy aircraft.
