Llangaffo Church (the church of St Caffo) is located in Anglesey North Wales. There are several items of interest at the church including a remarkable collection of inscribed and decorated stones, dating from the 7th to 12th centuries. The earliest stone in the collection, a wheel-cross gravestone in the sacristy, dates from the 7th Century. Five more stones stand against a low wall opposite the church door and other stones can be found in the graveyard walls.
