The last episode of Alberto Angela's trip to Italy presents a special trend. In fact, we will start from a privileged place: the Quirinale, the seat of the Presidency of the Republic. Ours will be a discovery not so much of this magnificent palace but of what it represents, that is, of our heritage, of the many natural and artistic riches scattered throughout Italy. It's as if we were here, in the Italian house, taking inventory of the family possessions. From Palazzo Alberto Angela will move to show the wonders of Italy. After a look at the engravings of Val Camonica, the first site in our country protected by UNESCO, we will go to Genoa, the superb city, the ruler of the seas, with its lantern and Palazzo Doria. The best man will be a Genoese in love with his city: Luca Bizzarri. We will move to the south, to Sicily, among the lunar landscapes of Etna, the most active volcano in the world, an alternation of fire and snow.
