The Electoral Palace in Amberg was built from 1417 by Louis III, Elector Palatine, and replaced the Alte Veste, a Gothic building in the town center, as the electoral court. The original building on the north was added with a south wing, a moat and a gatehouse, by Elector Frederick I turning it into a fortress. Its present appearance with a high voluted gable was set in 1603 by Johannes Schoch, who redesigned the Zeughaus with an added tower on the south. On 1738 horse stables were built as a western wing.
After several large fires in the 17th century, only the south wing (Neues Schloss) remains from the once three-winged palace. It is connected through the fortified bridge Stadtbrille, to the Zeughaus (armory) across the Vils river.
Having served the Electors of the Palatinate from its construction to the abolition of the Electorate, the castle was home, since the 19th century, first to the Royal Bavarian District office and Revenue office, later the District Office of the Bavarian State Amberg District and from 1972 of the District of Amberg-Sulzbach.
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.
