We’re back in the studio with senior properties curator Dr Mark Douglas to mark the 950th anniversary of Richmond Castle in North Yorkshire. Towering above the river Swale in the heart of the Yorkshire Dales, the castle is one of the finest and most complete Norman fortresses in the country, with a history stretching from the Norman Conquest to the First World War. Listen to discover why it was built, what life was like here through the ages and how it became home to the Richmond Sixteen.
