St Beuno's Church, Aberffraw

St Beuno's Church, Aberffraw is a 12th-century parish church in Anglesey, north Wales. A church was established in Aberffraw in the 7th century by St Beuno, who became the abbot of Clynnog Fawr, Gwynedd. St Beuno's may have been used as a royal chapel during the early Middle Ages, as the Princes of Gwynedd had a royal court in Aberffraw, as part of the Kingdom of Gwynedd. The oldest parts of the church date from the 12th century, although it was considerably enlarged in the 16th century when a second nave was built alongside the existing structure, with the wall in between replaced by an arcade of four arches. Restoration work in 1840 uncovered a 12th-century arch in the west wall, which may have been the original chancel arch or a doorway to a western tower that has been lost. The church also has a 13th-century font, some memorials from the 18th century, and two 18th-century copper collecting shovels. The church is still used for worship by the Church in Wales, one of four in a combined parish. As of 2013, the parish is without an incumbent priest. St Beuno's is a Grade II* listed building, a national designation given to "particularly important buildings of more than special interest", in particular because it is a "rare Anglesey example of a double-naved church", with elements including the "unusually fine" 12th-century arch. A 2009 guide to the buildings of the region says that St Beuno's contains "some of the most significant Romanesque work on the island".
