The knights of the Teutonic Order originally founded the Alden Biesen commandery in the 11th century, but the current buildings were constructed between the 16th and 18th centuries. It was the headquarters of a bailiwick or province of the Teutonic Order in the region of the Maas and Rhine. On 8 March 1971 the building burnt down and was acquired by the government and restored. In addition to the moated castle, the complex contains a church and gardens.
The castle is used today as a cultural centre and conference centre. Festivals such as the Scottish weekend or the International Story Festival are held there.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
