The Cathedral of St Nicholas is a Roman Catholic cathedral located in České Budějovice. The foundation stone of the parish church was laid around 1265, shortly after the founding of the city. The church of St Nicholas was consecrated in 1297, although it was still incomplete at the time. The completion of the main building probably occurred sometime around the mid 14th century. The original Gothic church was damaged by fire and repaired in the years 1513 - 1518. The church was significantly rebuilt several times. During the 16th century the church acquired a new bell tower called the Black Tower. In the 17th century, reconstruction took place and the church acquired its current baroque appearance. The church has a triple nave layout with 18th century interiors. In 1785 the interior was renovated when the church was elevated to a cathedral due to the creation of the Diocese of České Budějovice.
A cemetery was located beside the church and was in use from the Middle Ages up to the year 1784, when the decree of Joseph II forbade further burials. Between 1969 and 1971 internal adjustments were made in the cathedral in order to improve the liturgical space after the changes made during the Second Vatican Council.
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.
