Roche Castle is a late 13th century stone fortified manor house, founded by the de la Rupe family. The manor house, with its vaulted basement and first floor hall, was originally encased by a walled courtyard. Supported on a large polygonal moated platform, its shallow ditch was once filled from the adjacent stream. Standing to the south-west, are the buried foundations of rooms and a fragment of a wall, which is flanked on the angle by a semi-circular turret. This is all that remains of the castle, after it was pillaged for building stone in the 17th century. A mile north-east is Laugharne Castle.
