Every year FAI (Fondo Ambiente Italiano) celebrates spring with an event dedicated to the cultural heritage of Italy with special openings and guided visits. Over 1.100 places like villas, palaces, castles around Italy, most of them usually closed or unknown to public, open their doors thanks to the FAI volunteers.
