St Cewydd's church, Aberedw, is a medieval church said to have been founded in the C6, but the present building is 15th and 16th century. The nave and chancel are the oldest surviving part, then the tower and finally the porch. The church was restored by S.W. Williams, architect of Rhayader, in 1888, and further restoration was carried out in 1914.

Wallpaintings: There are C18th painted texts in English.
