Llangoed Hall, originally known as Llangoed Castle, was donated to the church in 560 by Prince Iddon in expiation of his sins, and is believed to have been the legendary White Palace, home of the first Welsh parliament.
A mansion existed from 1632. It was first in the possession of the Macnamara family having been won in a game of cards and it stayed with them for two generations until 1847. In 1912 Clough Williams-Ellis re-designed the mansion as a country house, retaining the surviving Jacobean porch as part of the south wing. Sir Bernard Ashley bought Llangoed Hall in 1987 and opened it as a hotel in 1990.
