St Leonard's Tower, West Malling

St Leonard's Tower is a probable Norman keep in West Malling, in the county of Kent, England. The tower was probably built by Gundulf, the Bishop of Rochester, between 1077 and 1108. It was a three-storey building, constructed of local stone, and would have stood at least 22 metres (72 ft) high. At a later point, probably during the English Civil War, the tower was deliberately damaged to prevent it being used for military purposes, and its uppermost storey was demolished. Concerns grew about the tower's condition in the 20th century and in 1937 it was taken into the guardianship of the state. In the 21st century, it is managed by English Heritage and the exterior is open to visitors.
