Corfe Castle is a fortification standing above the village of the same name in the English county of Dorset. Built by William the Conqueror, the castle dates back to the 11th century. The castle underwent two sieges - the first, in 1643, was unsuccessful, but the second was successful and ended in an assault. In March that year Corfe Castle was demolished on Parliament's orders.
