The Château Moncade is a ruined castle in the commune of Orthez in the Pyrénées-Atlantiques département. Construction of the castle was started in 1242 by the Gaston VII, Viscount of Béarn (the keep, known as the tour de Moncade) taking advantage of the absence of Edward III. When the King returned, Gaston was imprisoned and had to swear allegiance before being released. He subsequently reneged.
It was the residence of the Kings of Béarn when their capital was Orthez. Standing on top of a hill above the town, it afforded views of the surrounding county over a radius of more than 30 kilometres. The central tower was surrounded by high curtain walls and moats up to 15 metres deep. Entry was by a drawbridge.
In the 14th century, Gaston Phébus, Count of Foix, altered it between 1368 and 1375. The castle was burned during the Wars of Religion in 1569. It was sold during the French Revolution to dismantlers who largely demolished the curtain wall.
The only remains are the keep (in a good state of preservation), the moats (in course of restoration) and remnants of the curtain wall. The castle is open to the public (paying) and contains, among other items, a model of the site.
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.
