Witton Castle at Witton le Wear, to the west of Bishop Auckland stands at the entrance to Weardale. It was once the seat of the Eure family but, later passed into the hands of the Lambtons. For many years the castle was the home of the famous Red Boy portrait by Sir Thomas Lawrence, a painting of the only son of John George Lambton, first Earl of Durham. Today the painting is part of that family's London collection.
