Corfe Castle is a fortification in the English county of Dorset. It stands above the village of the same name. The castle dates back to the 11th century, and commands a gap in the Purbeck Hills on the route between Wareham and Swanage. The majority of the road traffic to and from the Swanage area passes below the battlements of the castle.
The oldest surviving structure on the castle site dates to the 11th century, although evidence exists of some form of stronghold predating the Norman Conquest. Edward the Martyr was assassinated at the site on 18 March 978.
