Ammersoyen castle was originally built in 1350 by Dirk van Herlaer along the river Maas. Ammersoyen was a unique castle as it was built using a fixed plan, which was unlike other castles built during this era. The design included four wings that were constructed around a center court. Each corner had its own heavy tower for extra protection. The castle included a gatehouse and was originally surrounded by a moat. At the time, it was one of the finest defensive structures in the country.
In 1386, the castle was lost to Duke of Gelderland who gave the castle to his illegitimate son. He then sold the castle in 1424 to Johan van Broekhugen, Lord of Waarenburg. For the next four hundred years, the castle only exchanged hands through inheritance.
Throughout history the castle was besieged several times with 1513 and 1574 being some of the more notable events. The castle suffered the most damage in 1590 when the castle owner Joris van Arkel was killed from his injuries. After his death, the castle fell into ruin until the 17th century when the Van Arkel family finally raised enough money to restore the castle. Thomas van Arkel paid the French 7,000 guilders to save the castle in 1672 when France swept through Holland and burned many castles along the way. The castle may have survived, but Thomas remained in debt and was never able to finish the castle renovations. After his death, the castle was inherited by another family.
The castle was then sold to the Roman Catholic Church in 1876 and was used as a convent. During World War II, the castle was used as shelter for village residents. Once the war was over, the castle was used as a village hall until it was purchased by the Gelderland Castle Trust in the late 1950s. It has since been restored to its former medieval glory.
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.
