Gloddaeth Hall originated as a large country house in Llandudno, Caernarfonshire (now Conwy), Wales. It is designated by Cadw as a Grade I listed building. It stands on land which had been owned by the Mostyn family since the 15th century.
The core of the building is a 16th-century hall and two storey solar block, built of stone rubble with freestone dressings.[1] There are gabled stone slate roofs. The hall is open to the hammer beam roof. The lower room of the solar has 16th century panelling, the upper room has a 17th century panelling. A wing to the east was added around 1700.
In the 19th century, further additions were made to the building by William Nesfield, and John Douglas, who designed a new west wing for Augusta, Lady Mostyn in 1889.[2]
A 17th century dovecote remains. Some elements of the formal gardens to the south-east may also be 17th century. The gardens are designated Grade I on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.
The hall now forms part of St David's College, a mixed sex independent boarding and day school for pupils aged 9–19. Tennis player Angela Buxton attended school at Gloddaeth Hall.
