Crevecoeur Tower is one of the series of towers in the western defences of Dover Castle, originating in the reign of King John (1199-1216), and unusually of round plan, and possibly used as a chamber tower with an adjacent hall. The tower is different from the others to the south, being round, more like the Norfolk Towers of the north gate of square plan, and seems likely to have been connected with an internal building.
