The Church of Saint Mary is a Grade I Listed Building in the town of Kidwelly, Carmarthenshire, Wales. Founded c. 1114 the church was burnt down in 1223 and most of the existing building dates from c. 1320 when it was a Benedictine priory.
It has been listed as the largest parish church in south west Wales, exceptional for the broach spire and fine decorative 14th-century Gothic detail.
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.
