The Palais du Rhin, the former Kaiserpalast (Imperial palace) is a huge building, it and the surrounding gardens, as well as the neighbouring stables, are an outstanding landmark of 19th-century Prussian architecture. After the Franco-Prussian War, Strasbourg, then German, was faced with the question of an official residence for the Kaiser. The decision was made to create a building symbolic of imperial power, and after much debate, a square Neo-Renaissance design was chosen, remotely inspired by the Palazzo Pitti in Florence. The architect was Hermann Eggert (1844–1920), who had already built, among other things, the Observatory of Strasbourg.
Work began on March 22, 1884 in honour of William I's 87th birthday, and construction took five years. The project received a good deal of criticism, with many questioning the need and use of the building, its appearance, and its price of three million marks. Inaugurated by William II in August 1889, the palace housed the emperor for twelve visits down to 1914.
During the First World War, the building was converted into a military hospital and in 1920 it adopted its current name when the oldest of the European institutions, the Central Commission for Navigation on the Rhine, moved in. In 1923, the palace passed hands to the French state and today houses the department of fine arts and the national furniture of Alsace-Lorraine.
Transformed into the 'Kommandantur' by the Nazis between 1940 and 1945, the building was recaptured by the troops of General Leclerc, who transformed it into their general headquarters. It was there that he wrote his proclamation announcing the realization of his oath at Kufra, proclaiming that he would fight until the French flag flew again over the cathedrals of Strasbourg and Metz.
Threatened with destruction in the 1970s, the palace, classified as monument historique since 1993, also houses the Direction régionale des Affaires culturelles of Alsace.
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.
