Château de Sedan is a castle situated in Sedan, France, near the river Meuse. Covering an area of 35,000 square metres in its seven floors.
Around 1424, Eberhard II von der Mark built a manor with two towers around a church over a period of six years. When Eberhard died in 1440, his son Jean de la Marck began reinforcing the fortress, but it was Robert II de la Marck, the grandson of Jean, who finished the most important work. In 1530, the fortifications of the manor were modernised by the construction of a circular boulevard and terraces with cannons, thickening the 4.5-metre curtain wall by an additional 26 metres (85 ft). The bastions were added during the course of the next century, but some of them were eventually dynamited at the end of the 19th century. In 1699, the principality having been absorbed into France in 1642 (during the Thirty Years' War), and the castle having been transformed into a garrison, Vauban built the door of the Princes that was adapted to the progress of artillery. In 1822, the Church of Saint-Martin was demolished and replaced with a store for cannonballs.
On September 1, 1870 during the Franco-Prussian War, the Army of Chalons was defeated at the Battle of Sedan. Napoleon III surrendered the following day in the small neighboring city of Donchery.
The castle was used as a military hospital by the German army in World War I. Sedan was also the site of a French loss to the Germans in World War II in the Battle of Sedan (1940).
The castle was given by the French Army to the city of Sedan in 1962. Today the castle contains a hotel and a museum showing the lives of inhabitants throughout its history and the Franco-Prussian War.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
