The Marekerk church was designed by the city architect Arent van ’s-Gravesande in 1639-1649, who also designed the Bibliotheca Thysiana on Rapenburg 25. It was opened in 1649. The main entrance was designed by Jacob van Campen in 1659. The organ was built by Pieter de Swart around 1560 for the choir of the Pieterskerk and it was moved to the Marekerk in 1733 and enlarged by Rudolph Garrels. It was restored in 1966 by Flentrop Orgelbouw.

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.
