An impressive ruin near the deserted medieval village of Whorlton and this was just the gatehouse. The castle itself, of the motte and bailey type, was probably built during the reign of Richard II and was already a ruin when this gatehouse was built. A lot of the stone has been robbed to build the nearby village of Swainby.
The building is privately owned and is open to the public which has made it a target for vandalism and a meeting place for teenagers. It was the subject of a BBC programme not so long ago called “Restoring England’s Heritage”, which unfortunately is not available on iPlayer. As a Grade 1 listed listing any restoration work is problematic but as I recall the owner is trying to raise funds to convert the 14th century gatehouse into a house/holiday let by the dropping in of a prefabricated steel box. Estimated costs for all this to be of the order of £2m.
