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:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
