The Church of St Margaret Marloes dates from the 14th and 15th centuries with restoration work being undertaken in 1878 and again in 1900. The church has a round churchyard, an indication that this site has likely been used since prehistoric times. A tombstone dating back to the fifth century was found in the churchyard. It is believed that Saint Cynin founded the church as one of a series of missionary stations in the fifth century.
An Ogham stone was found in the churchyard prior to 1900. The stone's inscription is in Latin and Celtic, with the word 'ingenia' being substituted for the Latin word 'filia'. This type of Ogham stone inscription was common in Ireland, but was the only example of it outside of Ireland when it was discovered at the church.
The church is a small building set in a hollow. It was said to be ruinous in 1710 and has a sprocketed, eighteenth-century roof. There is good stained glass windows, and a large carved oak altar and church fittings dating from 1882. Margaret Marloes, to whom it is dedicated, was the niece of Guy de Brian, Lord of Laugharne; a fourteenth-century effigy of her was brought inside the church from the churchyard in 1902 as it was getting badly eroded.
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.
