History
Castellated house of the early C19, built c. 1812 for George Jeffreys, High Sheriff 1819. The Jeffreys family came to the area c. 1760 when Edward Jeffreys of Shrewsbury bought a partnership with Henry Bowdler of Shrewsbury in the revived lead smelting mills of 1704-6 at Garreg. He bought part of the Ynyshir estate from Mrs Skyrme of Shrewsbury in 1792, presumably including the castle site. Edward Jeffreys died 1801, his son Robert in 1802, Robert's son Edward died in Portugal as a soldier in 1812, and the estate passed to his brother George, a barrister, who built the castle and was resident by 1818. George Jeffreys and his wife were friends of the author Thomas Love Peacock, who was married from Glandyfi Castle in 1820. Marked on 1845 tithe map as having 52 acres (21.06 hectares). George died in 1868, his son Edward died in 1888, and Edward's brother Charles died in 1904. The family sold the castle with 370 acres (149.85 hectares) in 1906 to Lewis Pugh Pugh, formerly of Abermad, who kept the land and sold the castle with 43 acres (17.42 hectares) to Major later Lt-Col R. J. Spurrell (born 1855), originally of Bessingham Manor, Norfolk. He had retired in 1905, but was re-called 1914-17 to command the 13th Royal Sussex Regiment. Still owner in 1926. Sold 1944 by a Miss Davies to Rowland Pugh, formerly of Voelas. In 1949 said to have oak-panelled halls, 4 reception rooms, 8 bedrooms, 3 bathrooms and kitchen, and said to date in part from the C11. It was then sold to the BSA motorcycle firm, for the use of Sir Bernard Docker, director, but resold with little alteration.
There is no evidence that there was a Norman castle on the site. Evidence for a pre-1812 house is obscure but there are certain blocked openings in the service ranges that may suggest elements of rebuilding rather than a completely new structure.
Glandyfi Castle is the only castellated country house in the county, of the type being promoted by John Nash, the Reptons, and others in the late C18 and early C19. It has strongest similarities to Stanage Park, Knighton, by J. H. Haycock of Shrewsbury, c. 1810, who may have been the architect here. The suggestion that Clough Williams-Ellis altered the house c. 1950 is unproven.
