St. Paul's Church (Pauluskirche) was constructed between 1898 and 1901 by Karl Moser (1860–1936) and Robert Curjel and features a Neo-Romanesque architectural style. The apse is fitted with a stone pulpit that is raised behind a stone communion table. The apse also features a gallery, with a central arch behind the pulpit, in which the organ and choir are placed.
It features artwork in Art Nouveau style including relief work on the church exterior above the main entrance by sculptor Carl Burckhardt (1878–1923), mosaics on the inner front wall by Heinrich Altherr (1878–1947) and stained glass windows by Max Laeuger (1864–1952).
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.
