Gwrych Castle is a fairly modern one as Welsh castles go. The castle was built around the mid 19th century long after the English/Welsh wars, so was never used defensively. Up until 18 years ago this castle/home was in an immaculate condition with a large marble main stairway large oak doors etc etc and was in use. Then bought by an overseas investor was allowed to fall into ruin. It has now been bought by an hotel chain who plan to fully restore it.
