The Church of St Michael is situated on a hillside on the western side of the Hoffnant Valley. The precise date that the church was completed is unknown, but there is believed to have been an earlier church on the site during medieval times. The Church in Wales states that it is of 12th century origin, making it the oldest in the diocese of St. Davids. The roof is likely as old as the 15th century, though the porch is believed to have been added much later in the early 17th century. The windows were added in the early 19th century.
In 1887 the church was extensively renovated by D. Davies of Penrhiwllan, and it underwent another renovation 70 years later in 1957, possibly under A.D.R. Caroe. The interior is whitewashed, and features slate floors. The Royal Commission on the Ancient and Historical Monuments of Wales notes that the limestone square in the interior dates to the original building of the 12th century, and that the square font and font in the porch also date to the medieval period.
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.
