Castle Upton is situated in the village of Templepatrick, in County Antrim, Northern Ireland. It is around 12 miles (19 km) north-west of Belfast. Originally the site of a 13th-century fortified priory of the Knights of St John, the present building was constructed around 1610 by the Norton family who settled here during the Plantation of Ulster. Soon after, it was bought by the Upton family, later the Viscounts Templetown, who remained in possession until the 20th century and whose family mausoleum is accessible to the public in the adjacent Templetown Old Burial Ground. The castle was remodelled in the 1780s to designs by the Scottish neoclassical architect Robert Adam, who also designed the stable block now known as 'Adam Yard'. Upton was purchased in 1963 by Sir Robin Kinahan and Coralie de Burgh, by which time it was in a poor state of repair. Following restoration the Adam Yard was converted to housing, and the castle later opened as a wedding venue.
