Margam Stones Museum is a small Victorian schoolhouse near Port Talbot, which now provides a home for one of the most important collections of Celtic stone crosses in Britain. All originally found within the locality of Margam, and mostly assembled as a collection in the 19th century, they provide enduring testimony to a Welsh Christian culture between the 6th and 16th centuries.
The striking Cross of Conbelin is the most celebrated example. From around 1000 AD, it is a huge disc cross with Celtic interlace and plaitwork patterns, figurative scenes including a hunting scene, and inscriptions telling us who made it and who erected it. There are 17 early Christian stones, plus 11 memorials and other stones from the post-Norman periods. The museum is run by Cadw, the Welsh historic sites agency, and is close to Margam Abbey Church and the ruins of the Abbey buildings.
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.
