In this episode Alberto Angela takes us through the extraordinary scenery of Castel del Monte and the Trulli of Alberobello in Puglia. We will explore the forgotten world of the Etruscans by discovering the treasures of the National Etruscan Museum of Villa Giulia - gold, jewels, the moving sarcophagus of the spouses...- and the magnificent tombs of Cerveteri and Tarquinia with paintings that have remained intact which describe a world full of colors and love for life. The panorama changes decidedly in the last stage of Meraviglie's journey. We are in Veneto, with the splendid Palladian Villas, the jewel in the crown of our heritage and the fruit of the genius of Andrea Palladio, the Renaissance architect who was responsible for the refuge villas of the aristocracy and bourgeoisie of the time but also production centers with their fields, vineyards, warehouses, stables.
