Thought to be a C16 and later house, two storied, with whitewashed stone walls and a modern roof (1956); the walls are generally 1.2m thick and shows stone mullioned window frames, some blocked. Thought to have been the site of a castle, demolished by 1639; an episcopal palace is recorded as having been built at Llanddewi, 1328-47, demolished 1362-89 because of a lack of water. OS County series (Glamorgan XXXI.1 1879) shows remains of an enclosure/structure, 12m by at least 25m N-S, immediately W of current house, with the legend 'Castle (remains of)': possible traces of this structure apparent on AP. (Coflein)

The present farmhouse, which is said to have been built on the site of LLanddewi castle, dates from the Tudor period, but recent repairs have obliterated ancient features. The castle had been demolished by 1639. The farmhouse is a two-storeyed building with whitewashed stone walls and a modern roof. The walls average 1.2m thick and contain the frames of stone mullioned Tudor windows, some of which are blocked in. No remains have been found of an earlier structure.

Gatehouse Comments

Spurgeon writes a castle here seems most improbable.
