The elongated church (), a conglomeration of distinct buildings, is divided into two areas by a wall, a 13th-century monastery church, and the Norman parish church. The eastern section contains interesting medieval wall paintings with religious themes, and a fine reredos. The western section, a Lady chapel, in length, has an inscription to King Rhys ap Arthfael of Morgannwg who died in the mid-9th century. The church contains a curfew bell and medieval priest effigies. The older church is long; the newer church was built by Richard Neville.
