The church of St Agatha, an entirely Victorian rebuild, is wholly in Shropshire although a small part of the churchyard is in Powys. The dedication is an unusual one, for Agatha was a Sicilian saint during the Roman era, and its appearance in the Welsh marches is unexplained, though as Archdeacon Thomas speculated in the 19th century, it could be a rededication stemming from the patronage of a returning crusader.
