Built entirely in 1248, the church of the Trinitarians is one of the finest expressions of Gothic art in Luxembourg. The large choir was added in 1644. The main altar, made in 1758 in Rococo style, is the work of the artist Michel Weiler. Beside the church, the former cloister of the Trinitarians (1250). The recumbent effigy of Marie de Spanheim (approx. 1400) preserves the memory of the last descendant of the Counts of Vianden.
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.
