Old Beaupre Castle (Welsh: Hen Gastell y Bewpyr; also known as Beaupre Castle, Old Beaupre Manor, or simply Beaupre) is a ruined medieval fortified manor house located in the community of Llanfair, outside Cowbridge in Wales. It is known in historic documents under the names Beawpire, Bewerpere, Bewpyr and Y Bewpur. It is a Grade I listed building and is presently under the care of Cadw. It can be visited free of charge all year round by members of the public.
Although called Old Beaupre Castle the structure is seen as a fortified manor house. The original house was an L-shaped building, now located within the inner courtyard, built circa 1300 and from this period until the 18th century it was owned by the Basset family. During the 16th century intensive remodelling was undertaken, started by Sir Rice Mansel, continued by William Basset and completed by William’s son, Richard. This additional work added the impressive outer gatehouse, completed in 1586 and a three-storeyed Renaissance porch, completed 1600, along with the buildings around the middle court.
