One side of the main street in the village of Templepatrick consists of the 18th Century demesne wall of Castle Upton. An impressive fortified gateway in the wall at the centre of the village leads up to the castle. The core of the main house is a tower house, originally thought to be part of a Commanderie of the Knights of Saint John (Hospitallers) with walls up to five feet thick, and the main bulk of the building was created in 1611 by Sir Robert Norton and originally known as Castle Norton.
