Severndroog Castle \u2013 \u201cLady James\u2019s Folly\u201d \u2013 is an eighteenth century tower located in Oxleas woods in Southeast London.  It was built as a memorial to Commodore Sir William James, a former chairman of the East India Company by his wife Lady Anne James in 1784. Designed by architect Richard Jupp and based on Shrubs Hill Tower in Windsor<\/a>, the triangular tower is 19 meters high with three storeys and a viewing platform. It stands within ancient deciduous woodland at the top of Shooter\u2019s Hill \u2013 one of the highest natural points in London.<\/p>\n\n\n\n

An inscription on the stone tablet above the entrance reads:<\/p>\n\n\n\n

This building was erected MDCCLXXXIV by the representative of the late Sir William James, Bart. To Commemorate that Gallant Officer\u2019s Atchievements (sic) in the East Indies during his command of the Company\u2019s Marine Forces in those seas. And in a particular manner to record the Conquest off the Coast of Malabar which fell to his superior Valour and able Conduct on the 2nd day of April MDCCLV.<\/p><\/blockquote>\n\n\n\n
