Fodor's Expert Review Église Saint-Maclou

Built on a rocky promontory in the heights of the old town, this ancient church—a classified historic monument—dates to the 11th century and was expanded in the 19th century. The relics of Saint Honorine, which originally arrived in the city in 876 and for which the town is partly named, were removed for protection in the 12th century but found their way back here after the French Revolution. Their journey is depicted in a beautiful window over the chapel of Saint Honorine. The church also houses the tombs of Mathieu IV de Montmorency and Jean Ier, important nobles who were interred here in the 14th century, followed by various family members up to the 17th century.
