The three castles of Husseren-les-Châteaux (Les Trois Châteaux d’Eguisheim), alternatively referred to as the three castles of Eguisheim, stand in the French Vosges in upper Alsace. The group of castles is variously named after the nearby town of Eguisheim, or the village of Husseren-les-Châteaux.
The three castles, from north to south called the Dagsbourg, the Wahlenbourg and Weckmund Castle, were built close to one another, but not at the same time, on a low hill ridge. This type of arrangement, with a cluster of three castles, is found in several places in the Vosges and the nearby Palatine Forest in Germany, for example the Dreistein on the Odilienberg, the cluster of castles at Ochsenstein near Saverne, the Hohkönigsburg and the castles at Dahn.
Wahlenbourg is the oldest of the three castles. It was constructed in 1006 by Hugues IV, Count of Eguisheim and his wife Heilwige, Countess of Dabo, on the site of a Roman watch tower. In 1026, the castle was destroyed by Duke Ernest of Swabia. The edifice was divided into three distinct parts: at the top was the Count's Residence, below was accommodation for family retainers and officers, then at the bottom were barracks for soldiers and the stables.
Dagsbourg was built in 1144 by the Count of Ferrette but in 1197, after a revolt against the Emperor Henri IV, it was destroyed by Philip of Swabia, the Emperor's brother.
Weckmund: At the death of the last direct descendant of the Counts of Eguisheim-Dabo in 1225, the Counts of Ferrette became the closest heirs, but their claim was disputed by the Bishop of Strasbourg who declared war and occupied the castles of Eguisheim. In 1226-1227, King Henry of Germany, ally of the Counts of Ferrette, built this siege tower in the mower yard to control access to the castles. When peace returned, the Bishop retained the Dagsbourg and the Weckmund reverted to the Count of Ferrette.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
