The Electoral Palace was the residence of the last Archbishop and Elector of Trier, Clemens Wenceslaus of Saxony, who commissioned the building in the late 18th century. It was erected between 1777–1793. In the mid-19th century, the Prussian Crown Prince (later Emperor Wilhelm I) had his official residence there during his years as military governor of the Rhine Province and the Province of Westphalia. It now houses various offices of the federal government.
The Electoral Palace is one of the most important examples of the early French neoclassical great house in Southwestern Germany, and with Schloss Wilhelmshöhe in Kassel, the Prince Bishop's Palace in Münster and Ludwigsburg Palace, one of the last palaces built in Germany before the French Revolution. Since 2002 it has been part of the Rhine Gorge UNESCO World Heritage Site, and it is also a protected cultural property under the Hague Convention.
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.
