This cathedral’s calm green façade belies its astonishingly luxurious interior. Marble columns, furnishings decorated by mosaics in colored stone (marquetry), gold mouldings, and massive murals combine to create true baroque splendor. Built by architect Jean-André Guibert - one of baroque art’s greatest supporters - between 1650 and 1699 in honor of Saint Réparate (the city’s patron saint), the church consists of three naves and a magnificent chancel. The bell tower was added almost a century after the cathedral was completed. Relics abound, as do several interesting paintings, including one by early 19th-century local artist Hercule Trachel.
