To Zero transforms the ruins of Santa Maria di Settefonti, on the historic Gothic Line, into a multi-faith centre for peace. An independent structure sits entirely detached from the original walls, preserving their scars as a solemn reminder of war. The "War Clock" on the façade monitors active global conflicts. Inside, ethereal light filters through an opal roof, while a structural glass floor reveals the Romanesque foundations beneath. A monumental east-facing window serves as a universal focal point for all the world's prayers.
