The old parish churches are of medieval origin, their main period of construction being late 12th to mid 14th century. All have been altered over the centuries, and most were heavily restored in the 19th century.


All the churches of the Benefice are open to visitors during daylight hours throughout the year, with the exception of Llangan and St Mary Church. Information regarding the location of keys to allow access to these two churches is posted on the church notice boards at both locations, as is information regarding out of hours access at each of the other churches.
