Geeraard de Duivelsteen is a Gothic building in Ghent, Belgium. It served as defense of the Portus Ganda, the city's port. The building was built in the 13th century and was named after the knight Geeraard Vilain (1210-1270), second son of the fifteenth viscount of Gent, Zeger III of Ghent. Vilain's nickname was Geeraard de Duivel ('Geerard the Devil'), which was based on his dark complexion and hair color.
In the 14th century the building became city property. Over the course of centuries it was used for various functions; gatherings of knights, as an armory, a monastery, a school, a bishop's seminary, an insane asylum and a prison. In 1775 the Rasphuis near the Coupure channel became the new prison. In 1830 the Geeraard de Duivelsteen became a fire station. Near the end of the 19th century it was bought by the Belgian state to serve as a national archive. For this purpose a new wing was built. Due to the numerous restorations the building has changed a lot since the Middle Ages.
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. The county became a privileged refuge for persecuted Cathars.
The castle, often besieged (notably by Simon de Montfort in 1211 and 1212), resisted assault and was only taken once, in 1486, thanks to treachery during the war between two branches of the Foix family.
From the 14th century, the Counts of Foix spent less and less time in the uncomfortable castle, preferring the Governors' Palace. From 1479, the Counts of Foix became Kings of Navarre and the last of them, made Henri IV of France, annexed his Pyrrenean lands to France.
As seat of the Governor of the Foix region from the 15th century, the castle continued to ensure the defence of the area, notably during the Wars of Religion. Alone of all the castles in the region, it was exempted from the destruction orders of Richelieu (1632-1638).
Until the Revolution, the fortress remained a garrison. Its life was brightened with grand receptions for its governors, including the Count of Tréville, captain of musketeers under Louis XIII and Marshal Philippe Henri de Ségur, one of Louis XVI's ministers. The Round Tower, built in the 15th century, is the most recent, the two square towers having been built before the 11th century. They served as a political and civil prison for four centuries until 1862.
Since 1930, the castle has housed the collections of the Ariège départemental museum. Sections on prehistory, Gallo-Roman and mediaeval archaeology tell the history of Ariège from ancient times. Currently, the museum is rearranging exhibits to concentrate on the history of the castle site so as to recreate the life of Foix at the time of the Counts.
