Elaborate ornamentation, especially in the arches of the doorways (figures of Adam and Eve by Tilman Riemenschneider – the originals are now on display in the Mainfränkisches Museum, replaced by replicas from 1975).
Interior was replaced after fire damage in 1945. The altar features four panels with paintings from 1514. Famous “Beautiful Madonna” (around 1420) and Silver Madonna (17th century). Numerous tombs of Franconian knights and citizens of Würzburg, including the tomb of Konrad von Schaumberg (died 1499) by Riemenschneider and the tomb of the great Baroque architect Balthasar Neumann (1687-1753) at the market gate.
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.
