Castle Upton is a 10,398 square feet (966.0 m2) castle situated in the village of Templepatrick, County Antrim, Northern Ireland.
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.
One of the notable achievements of this castle is the reconstruction of the wrecked Adam wing. This wing, now contains a ballroom in which an Italian, marble chimney has been added. The owners of this castle obtained this chimney from the Downhill Castle in the County Londonderry. Danny Kinahan MP and his wife are the current owners of Castle Upton.
The castle was purchased in 1625 by Captain Henry Upton, who became Member of Parliament for Carrickfergus in 1634 and renamed the building. The stable block was built from exact architectural copies of the now demolished old Fish Market of Leith, near Edinburgh, Scotland.
