St Brides Castle

St Brides Castle stands in Pembrokeshire, southwest Wales, as a 19th-century castellated baronial-style mansion. It occupies the site of an earlier 18th-century house that replaced an ancient mansion to the west. Topographer Richard Fenton described the earlier building in 1811 as an elegant modern structure. The estate once covered 348 acres in 1839. The house was enlarged between 1905 and 1913 for the 6th Baron Kensington.

The present building mixes Tudor, Gothic, Edwardian and Scots Baronial styles. Rubble stone and sandstone form its walls under slate roofs. Nikolaus Pevsner suggests Thomas Rowlands may have been the architect. The early-20th-century expansion is regarded as the last major country house work in Pembrokeshire. The castle is Grade II* listed for its late Georgian interiors and high quality Edwardian additions.

The grounds are Grade II on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. After renovation, the building now contains holiday apartments. The current owners are Holiday Property Bond. Original interior features remain throughout the house. The setting combines historic architecture with landscaped gardens.
