This atmospheric ruined palace was begun at the same time as St David's Cathedral, adjacent, but its final, imposing Decorated Gothic form owes most to Henry de Gower, bishop from 1327 to 1347. The most distinctive feature is the arcaded parapet that runs around the courtyard, adorned with a chequerboard pattern of purple and yellow stone blocks. The corbels that support the arches are richly adorned with a menagerie of carved figures – animals, grotesque mythical creatures and human heads.

　　Interesting displays within the basements and ruined rooms bring each part of the palace to life. The distinctive purple sandstone, also used in the cathedral, comes from Caerbwdy Bay, a mile southeast of St Davids.

　　The palace courtyard provides a spectacular setting for open-air plays in summer.
