Located in the armory of Palazzo Vecchio in Florence, the exhibition stages the result obtained from the international competition of ideas for the redevelopment of the cathedral choir, with projects from Botta, Brenner, Gabetti and Isola, Graves, Hollein, Isozaki, Nouvel, and Rossi. Around the two medieval octagonal columns designed by Arnolfo di Cambio, the project included the design for the rooms dedicated to contemporary architects and exhibitors. The main room was transformed into a fluid space filled with columns to punctuate the junctions of the exhibition itinerary.
