Around 540,000 Italians took part last weekend in the initiative promoted by the FAI (Italian Environment Fund), visiting for free 780 sites of art, history, and nature opened exceptionally to the public across 400 cities—many of them lesser-known or undervalued. The most visited site was the Diego Armando Maradona Stadium in Naples. Second place went to the Palace of Justice in Rome, home to the Supreme Court of Cassation; third to the Palazzo della Cancelleria, also in Rome; fourth to Porta Nuova and Cavallerizza at the “Sicilia” Army Command in Palermo; and fifth to the historic garden of Villa Sgariglia in Grottammare (Ascoli Piceno). The regions with the highest attendance were Lombardy, Emilia-Romagna, and Veneto. Among the most visited sites were also Villa dei Vescovi in Luvigliano di Torreglia, Villa Gregoriana in Tivoli, and Villa Necchi Campiglio in Milan.
