On the occasion of the Nuit des Arts, we invite you to take an urban stroll through the heart of the city center to discover these elegant buildings and the works of architect Jacques Gréber. Observe the many details of the Art Deco period, and admire the buildings designed by Gréber for families such as Tiberghien et fils, Prouvost et Lefebvre and Masurel Leclercq.
