Treasurer’s tower is one of a series of towers located along the south western outer curtain wall of Dover Castle. A tower was originally constructed here in the C12th/early C13th but was entirely reconstructed in the C15th during the reign of Edward IV (1461-1483). The tower is different from all of the others located along the south curtain in that it is polygonal (semi octagonal). Today it is incorporated within the garden of the Constables tower and residence which is a later addition. (location accurate to the nearest 1m based on available information)
