Here in the square in front of the Louvre there is a view of the church Saint-Germain-l'Auxerrois. It was the parish church of the Valois dynasty. On August 24th, 1572, on the day of St. Bartholomew on the orders of Catherine de Medici, the bells of this church signaled the beginning of the massacre of Huguenots, who were invited to the wedding of Henry of Navarre with Margarita de Valois, - so began the Bartholomew night. It is considered that they called from the main preserved tower, but this is not true: the Catholics were sounded by a small bell tower on the south side of the church.

From Wikipedia: Founded in the 7th century, the church was 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.
