In Northern Italy, a unique skyline emerges, combining the aesthetics of history and tradition with the innovations of modernity. Milan reveals itself through Stefano Boeri’s Vertical Forestand Rem Koolhaas’s Fondazione Prada, along with the imposing Milan Cathedral and the grand iron-and-glass dome of Galleria Vittorio Emanuele II. But the true essence of the metropolis lies hidden behind the façades of the striking buildings.

Author Massimo Nava and photographer Oberto Gili are happy to oblige.
