A castle was founded at Corfe near England's south coast soon after the Norman Conquest of England in 1066. The royal forest of Purbeck, where William the Conqueror enjoyed hunting, was established in the area. Between 1066 and 1087 William established 36 castles such in England. Sitting as it does on a hill top, Corfe Castle is one of the classic images of a medieval castle, however despite popular imagination occupying the highest point in the landscape was not the typical position of a medieval castle. In England, a minority are located on hilltops while most are in valleys; many were near important transport routes such as river crossings.
