Kintzheim was known in the 6th century under the name of Regis Villa. The Merovingian kings had made it into the center of a vast domain including the valley of the Liepvre River and the forests of Haut-Koenigsbourg.
The construction of the castle began around 1250 on the order of Emperor Frederick II of Hohenstaufen. The keep and the rampart which belongs to it were finished at the end of the 13th century. The residential structures were built during the 14th and the 15th centuries.
In 1633, the castle was partly destroyed by the Swedes during the Thirty Years' War. Between 1650 and 1670, J. G. de Gollen restored the residential buildings and the chapel, but never actually lived in there. Between 1760 and 1780, the last resident of the castle was a hermit monk who took care of the chapel.
In 1802, the future Baron of the Second Empire, Gaetan Mathieu de Fabvier, bought the castle, and below it he built a manor house in the Directory style. Between the two structures he built a park in the English style. He created a romantic landscape garden, or jardin tableau, to highlight the view of the ruined castle, inspired by the paintings of Nicolas Poussin, Claude Lorraine and Hubert Robert.
During the 19th century, the romantic movement brought medieval castles back into style. In 1876, German architects carried out a consolidation of the ruins of Kintzheim.
Since 1968, the Château de Kintzheim has featued La volerie des aigles ('The Eagles' Nest'), which presents species of predatory birds, such as eagles, falcons and vultures, which are in danger of extinction. Spectators can attend daily flights of the birds.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
