The Church of Saint-Germain-l'Auxerrois was originally founded in the 7th century, but it has been rebuilt many times over several centuries. It now has construction in Roman, Gothic and Renaissance styles. The most striking exterior feature is the porch, with a rose window and a balustrade above which encircles the whole church, a work of Jean Gaussel (1435–39). Among the treasures preserved inside are a 15th-century wooden statue of Saint Germain, a stone carved statue of Saint-Vincent a stone sculpture of Isabelle of France (saint), a Flemish altarpiece carved out of wood, the famous 'churchwarden's pew' where important people sat, made in 1683 by François, Le Mercier from drawings by Charles Le Brun.
During the Wars of Religion, its bell called 'Marie' sounded on the night of 23 August 1572, marking the beginning of the St. Bartholomew's Day Massacre. Thousands of Huguenots, who visited the city for a royal wedding, were killed by the mob of Paris. A splendid stained glass still remains, in spite of plunderings during the French Revolution. The north tower was added in 1860 and stands opposite the Mairie of the 1st Arrondissement (1859).
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.
