St Mary's Church is the village church. The date of construction is unknown, but is probably from some time between the 12th to 14th centuries. Some medieval stonework remains in three walls of the building. A chapel was added to the south side in the 16th or 17th century, and the church was altered and refurbished during the 19th century.  The church is still in use, as part of the [[Church in Wales]], and is one of five churches in a combined parish. It is a [[listed building|Grade II listed building]], a designation given to "buildings of special interest, which warrant every effort being made to preserve them",<ref name=Cadwlist>{{cite book|url=http://www.cadw.wales.gov.uk/upload/resourcepool/WhatIsListing_englishLR983.pdf|title=What is listing?|publisher=[[Cadw]]|year=2005|isbn=1-85760-222-6 |page=6}}</ref> in particular because of the retention of medieval fabric in a predominantly 19th-century building, and its "fine" memorials.<ref name=List>{{Cadw|num=5557|desc=Church of St Mary|access-date=4 January 2011}}</ref>
