Lindisfarne Castle

A fort was built on an outcrop in 1549, using masonry taken from the dissolved priory. When Scotland united with England the threat from the north disappeared and it was left derelict. From 1901 it was owned by Edward Hudson, a publishing magnate and the owner of Country Life magazine. He had it refurbished in Arts and Crafts style by Sir Edwin Lutyens, so it's a remarkably stylish interior, while Gertrude Jekyll created the walled garden. It passed through various hands until acquired by the National Trust in 1944. Opening times are tide dependent, but any day in summer that it's possible to get here, you'll find it open. Live webcam.
