List of historic houses in Wales
This is intended to be as full a list as possible of country houses, castles, palaces, other stately homes, and manor houses in the United Kingdom and the Channel Islands; any architecturally notable building which has served as a residence for a significant family or a notable figure in history. The list includes smaller castles, abbeys and priories that were converted into a private residence, and also buildings now within urban areas which retain some of their original character, whether now with or without extensive gardens.
