Driving through Purbeck, one thing dominates the sky as you approach: Corfe Castle, or more, the castle ruins. We are inside the castle walls, following the path towards the remaining towers on a sunny day that started to grey over.
The building of Corfe Castle. Corfe Castles position, dominating a gap in the Purbeck Hills, means it was probably a fortified site long before the Norman conquest of 1066. But it was William the Conqueror who founded the castle we know today when he made Corfe a key element in a network of fortifications built to cement his power over the defeated English.
