The Pieterskerk (St. Peter's Church) is one of the oldest in Utrecht. Its construction began in 1039 and it was inaugurated on 1 May 1048 by Bernold, Bishop of Utrecht (although the lost west towers were probably only finished about a century after the inauguration). Characteristic of the Romanesque style in which it is built are the church's large nave pillars, each hewn from one piece of red sandstone, and the crypt under the choir. The building is now used by the Walloon Church.
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.
