The lively Saint-Ambroise area is known for Atelier des Lumières, a digital arts center in a former iron foundry. Narrow streets, many with converted industrial buildings, surround the area’s namesake church, a Second Empire-era structure with soaring twin towers. Elsewhere, Rue Oberkampf is home to late-night bars and eateries, while hip neo-bistros and hotels are scattered throughout the neighborhood.
