St. Sebaldus Church is one of the most important and oldest churches of Nuremberg. It takes its name from Sebaldus, an 8th-century hermit and missionary and patron saint of Nuremberg. It has been a Lutheran parish church since the Reformation.
The construction of the building began in 1225. the church achieved parish church status in 1255 and was completed by 1273-75. It was originally built as a Romanesque basilica with two choirs. During the 14th century several important changes to the construction were made: first the side aisles were widened and the steeples made higher (1309–1345), then the late gothic hall chancel was built (1358–1379). The two towers were added in the 15th century. In the middle 17th century galleries were added and the interior was remodelled in the Baroque fashion. The church suffered serious damage during World War II and was subsequently restored. Some of the old interior undamaged includes the Shrine of St. Sebaldus, works by Veit Stoss and the stained glass windows.
The church had an organ by the 14th century, and another by the 15th. The main organ had been built in 1440–41 by Heinrich Traxdorf, who also built two small organs for Nuremberg's Frauenkirche. Until its destruction in the 20th century it was one of the oldest playable organs in the world. The Traxdorf organ was rebuilt in 1691. The modified case was destroyed by the Allied forces during a bombing raid on 2 January 1945.
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.
