St. Mary’s Church in Barth is a brick church built around 1300 and it was mentioned for the first time in 1325. The church was created in 3 building phases, where the choir to the east is its oldest part and built in the early Gothic style.
The organ, which was created by the Berlin organ builder Buchholz and his son, promises a unique sound and is one of the particularly valuable organ monuments in Germany. Its special quality lies in its own beautiful sound and in its historic significance. With its 42 original stops, the instrument is the largest preserved work in Germany of the Buchholz organ builders and is at the same time the great early work of the son.
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.
