Clytha Castle is considered one of the outstanding 18th-century follies of Wales. It was designed by John Davenport and built in 1790 by William Jones of Clytha House. He built it as a memorial to his late wife Elizabeth, last surviving child of Sir William Morgan of Tredegar House, with the purpose of ‘relieving a mind afflicted by the loss of a most excellent wife’.
