Harewood Castle was originally a mid 12th century stone hall house and courtyard fortress, founded by Robert de Lisle. In 1366, Sir William Aldeburgh built the rectangular tower house, on the steep slope, after he was granted a licence to crenellate by King Edward III. The main block of two storeys, is flanked by four angle towers, one being a plain entrance tower, with the chapel situated over the portcullis chamber. The lower kitchen wing is of four storeys, with a barrel-vaulted basement that contains the well. To the north-west, are the rectangular earthworks of a possible outer bailey and traces of an Elizabethan bowling green survive to the east. 6 miles north-east is Spofforth Castle and 10 miles east is Kyme Castle.
