Following the destruction of 1940, architects Georges Noël, Jean Bourgon, and Gaston Schmitt designed the reconstruction and redevelopment plans for Toul's city center. In 1950, construction began on the circular square intended to become the heart of the new city, serving as the central hub: the Place des Trois-Évêchés, now a listed 20th-century heritage site. Designed with great simplicity, it gives the city an image of robustness and discipline reminiscent of its military past. Because of its shape, the people of Toul also call it the "Round Square." Each year, this square is the focus of a colorful floral display eagerly anticipated by both locals and tourists. The theme of the floral arrangement is kept secret until its unveiling, much to everyone's delight. The element of surprise is guaranteed.
