Saint-Gervais-Saint-Protais is a Roman Catholic parish church located in the 4th arrondissement of Paris, on Place Saint-Gervais in the Marais district, east of City Hall . The current church was built between 1494 and 1657, on the site of two earlier churches; the facade, completed last, was the first example of the French baroque style in Paris. The organists of the church included Louis Couperin and his nephew François Couperin, two of the most celebrated composers and musicians of the Baroque period; the organ they used can still be seen today. The church contains remarkable examples of medieval carved choir stalls, stained glass from the 16th century, 17th century sculpture, and modern stained glass by Sylvie Gaudin and Claude Courageux. Saint-Gervais was a parish church until 1975, when it became the headquarters of the Monastic Fraternities of Jerusalem.
