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 Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
