Where it was filmed 'Citadel: Diana'

The Citadel: Diana series was filmed in various Italian locations: Milan, Gibellina, Palermo, Scopello (Trapani), Como, Rome, Pomezia, Ravenna. Locations also in Switzerland (Lugano, at the San Gottardo Pass near Airolo) and France (Paris).

The richness of the locations is one of the series’ strong points. In Milan, the main setting for the story, exteriors were filmed in piazza Duomo, of Palazzo Arengario, City Life, in the Porta Venezia district where Diana's house is located (the interiors were built on a sound stage), at Niguarda hospital and outside the Central station, with a chase on via Vittor Pisani that required over 70 security personnel and dozens of stunt vehicles.

In Sicily, locations included Gibellina, inside the large cretto, an imposing work of environmental art created by Alberto Burri and one of the most important in the contemporary Italian artistic panorama, a testimony to the devastating Belice earthquake that destroyed the town in 1968; outside the Chiesa Madre designed by Ludovico Quaroni; and inside the Consagra theatre, an unfinished work designed by the artist whose name it bears. Also worth mentioning are the beautiful tonnara of Scopello, Villa Igiea and streets in Palermo.

In Como, Villa Erba in Cernobbio, a jewel of late 19^th-century architecture, provided the location for the Zani family home. The taste and refinement of the family members are reflected in the choice of this elegant villa on the lake with its refined and precious furnishings, deco embellishments and family paintings alternating with works of contemporary art.
