 The chapel itself is dedicated to St Mary and was built in 1762, replacing an earlier 15th-century structure.It originally served as a chapel of ease for the parish church at Llanigon, but is now within its own ecclesiastical parish.With an interior of just 26 by 13 feet (8 by 4 metres), the chapel is one of the smallest in Wales and reminded diarist Francis Kilvert of an owl.
