Metz rewards a short stay when you stick to a tight list. The Cathedral of Saint-Étienne is the obvious anchor, its soaring nave and famed stained glass tours revealing why locals call it the Lantern of God, while the nearby Centre Pompidou-Metz adds a bold contemporary counterpoint with rotating world-class exhibitions. Wandering the Old Town, Vieux Metz, on foot ties the two eras together through cobbled streets and half-timbered houses, and a River Cruise on the Moselle offers a relaxed way to see the same skyline from the water. Together these picks cover architecture, art, and atmosphere without wasting a single afternoon.
