The Church of St Dyfnog, Llanrhaeadr-yng-Nghinmeirch, dates from the 13th century. The church is most famous for its Tree of Jesse window which dates from 1533.
The first mentions of the church occur in the Norwich Taxatio Ecclesiastica of 1254 and the Lincolnshire Taxatio of 1291. The South chamber and the door of the tower may both date from this time. The Jesse window, the church's most famous feature, dates from 1533. The window is reputed to have been removed and buried during the English Civil war to protect it from destruction. It was re-instated in 1661. The church suffered at the hands of Victorian restorers.
The church is constructed of limestone rubble with sandstone dressings and slate roofs. It has a double nave, a South chamber and a four-storey tower. The architectural historian Edward Hubbard notes the style as Perpendicular, with the possible exception of the tower door.
