Church building
St Beuno's Church is a place of worship located in the village of Clynnog Fawr, Gwynedd, Wales. It belongs to the Church in Wales, an Anglican denomination, and is one of six churches in the parish of Beuno Sant Uwch Gwyrfai. It is adjacent to St Beuno's Chapel, to which it is connected, and approximately 322 metres (352 yards) north-east of Ffynnon Beuno (Beuno's Well).
Beuno was a seventh-century Welsh abbot who founded a clas on the site of the present church and was later buried there. The church is significant for its architecture and fittings, and has been described by the Royal Commission on the Ancient and Historical Monuments of Wales as "one of the most notable [churches] in North Wales". It is a Grade I listed building.
