Godric of Mappestone was an Anglo-Saxon thane and landowner mentioned in the Domesday Book of 1086 as a tenant of Howel in modern Herefordshire. Godric is best known for the construction of the first timber version of Goodrich Castle, probably during the late 1080s, when it was originally known as Castellum Godrici, or "the castle of Godric". Victorian historians, however, believed the castle to date back further to the pre-Norman conquest days of King Canute, and the site may have been among a small number of Saxon fortifications along the Welsh border.
