Alberto Angela brings medieval Siena to life, with the help of some breathtaking aerial shots.

Daniela explains how to use the demonstrative adjectives questo and quello [this and that]. She also tells us about a third demonstrative adjective that, these days, is used only in Tuscany: codesto.

We are now in the heart of Italy: Tuscany. One of the most beautiful and important cities in Tuscany is Siena with its very particular piazza.

After Philip's baptism, there is a banquet with typical Sicilian food, and favors for the guests. And there also happens to be a stunning view of Palermo from the convent or monastery hosting the party.

Alberto Angelo tells us the fascinating story of how trulli are built. Some of the most characteristic trulli can be found in Alberobello.

Arianna explains what a casbah is, and she and Simone take us around to the Tunisian consulate and the old washhouse.

We visit the land of the trulli, curious dry stone huts. Alberto Angela gives us some background about these unique dwellings.

Marino meets Silvana and they start chatting by the sea. They discover that their professions are related (naturopathy and body-psychotherapy) and they enjoy sharing ways of looking at emotions and symbols.

As opposed to the classical palaces of the powerful, with their throne rooms and great halls, Castel del Monte has some smaller and more intimate spaces, conducive to more personal encounters. Over the centuries, the castle was exploited in different ways, well into modern times.

We visit some of the narrow alleys with names that have special significance. Arianna and Simone tell the stories of these names and show us some of the beautiful ceramic pots placed around the town.

After the baptism ceremony in the Palatine Chapel, Adriano takes us to another historically and artistically rich site in Palermo: the Convento di Baida [Baida Abbey]. In Italian, the term convento is used more commonly than monastero [monastery] and may house either male or female religious communities.

Alberto Angela takes us inside Castel del Monte and helps us imagine what it might have looked like when it was "alive." He uses the term piano nobile, which indicates the floor of a mansion where the noblemen or landowners lived, as opposed to the floors where the servants' quarters and kitchens would have been.

Arianna and Simone take us through the narrow lanes of Mazara to the little theater, built from leftover materials from ships, and on to the Casbah, full of ceramic artwork.

Edo is an illusionist, and with Eleonora's assistance, he shows us some tricks with newspaper cuttings and a deck of cards, all with Mount Vesuvius as a backdrop.

Wonderful aerial photography shows Castel del Monte and its crown-like octagonal shape. Frederick II was particularly fond of the castle because it was an ideal location to hunt small game with his falcons.
