St Mary's Priory Church

Although you wouldn't guess it from the outside, this large stone church has been described as the 'Westminster Abbey of South Wales' because of the remarkable treasury of aristocratic tombs that lies within. It was founded at the same time as the Norman castle (1087) as part of a Benedictine priory, but the present building dates mainly from the 14th century, with 15th- and 19th-century additions and alterations.
