Haamstede Castle (Slot Haamstede) was built originally in the 12th century and it probably consisted of a wooden keep on a motte, circled by a moat. There is also archeological evidence of Roman habitation on this site. Around 1200 this castle came into the possession of Floris IV, Count of Holland. In 1229 the castle went to the Lords of Zierikzee through an exchange with Floris IV. The new inhabitants of the castle called themselves Van Haamstede.
The castle was destroyed by fire in 1525. Only the keep, built in the 13th century, survived. The other castle was rebuilt in the 17th century. The keep was provided with 2 square towers on both sides. The smallest one served as a stair tower. During the 19th and 20th century the castle was renovated twice until it got its present appearance.
At present Haamstede Castle is owned by the Vereniging Natuurmonumenten, a society for the preservation of nature monuments in the Netherlands.

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.
