Assumption of Mary Church or the Rožňava Cathedral was built in 1304 and remodeled during the 15th and 16th centuries. During the 16th and 17th century the church was owned by Catholics and Protestants. With the establishment of the episcopal office in Roznava, the church became the cathedral. Subsequently extensive interior modifications were done. In 1836 the southern aisle was changed to the Chapel of Saint Neita, whose relics were brought here from Rome.
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.
