The Seminar New Forms of Complexity in Architectural and Urban De­sign, aimed at drawing attention on the chal­lenges of contemporary urban transformations by exploring the future of architecture through the key of complexity. Architects need to keep up with the times and the stringent challenges they present; therefore, they should be prepared and gain a full under­standing of the complex and interconnected systems we live in; at the same time, they need to adopt a long-term perspective and suggest a range of concrete measures in order to inspire habits and attitudes designed to re-es­tablish our connection with nature, among other things.
