Ludworth Tower was originally a medieval fortified manor house, founded by the de Ludworth family. In 1422, Thomas Holden added a rectangular tower house, when he was granted licence to crenellate his manorial complex, by Cardinal Langley. Sadly the only remains, are the barrel vaulted basement, the three storey west wall and fragments of a first floor spiral stair in the south wall. 6 miles west is Durham Castle.
