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

Antonino has a visitor from Sorrento on the Amalfi Coast, who brings in some of the world-famous Sorrento lemons. They prepare whole-wheat spaghetti with a simple sauce featuring lemon rind and bottarga (salted fish roe).

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.

Adriano has invited us to the baptism of his son Philip. It allows us to get a glimpse of one of the most beautiful places to visit in Palermo, the Palatine Chapel. The priest tells the congregation about the consecration of this famous basilica in 1040.

Arianna and Simone show us the historic center of this city on Sicily's west coast. Points of interest include its Casbah, where ceramic tile artworks tell of the city's Arab history, an unusual central-plan church; and the Satyr Museum.

In this last segment, Daniela focuses on when the past participle of a verb in the present perfect has to agree (in number and gender) with the direct object pronoun when using compound pronouns. It's a bit tricky.

The first stop is Italy's easternmost point, the Punta Palascìa and its 19th century lighthouse. Alberto Angela then shows us another site in the Apulia region, Castel del Monte, a breathtaking crown-shaped castle built by Frederick II in the early 1200s.
