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 court in Aberffraw. 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, with elements including the unusually fine 12th-century arch.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
