The City Church of Bremgarten is an important landmark. The church was built in 1300 and was consecrated in honor of Saint Mary Magdalene. In 1420 Anna of Brunswick-Lüneburg, the wife of Frederick IV, Duke of Austria, gave all rights to the church to the local hospital, under the condition that a mass in her memory would be served once per year. The mass is still being served. In 1529, in the course of the Reformation, the building was converted into a Protestant church, but in 1532 it became Catholic again, Since 1532, the church has been consecrated in honor of Saint Nicholas.
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.
