We visit the magnificent, immense Throne Room, with its small but elegant throne, and vaulted, frescoed ceiling.

It's hard to fathom the scale of this royal palace. We learn how many workers it took and how long it took to build. The grand staircase is of amazing dimensions, and, when seen from the top, our host seems like a small dot at the bottom of it.

Alberto Angela, well-known presenter of historical TV documentaries, takes us on a journey to discover some of the "wonders" — both man-made and natural — of this "treasure peninsula" called Italy. The journey begins at the Royal Palace in Caserta.

Mini decides to guide Arianna through one of the main roads of Lucca to the center of the city. It's one continuous road but its name changes several times. Arianna is fascinated by some mysterious numbers appearing on the stones of the pavement.

Arianna visits Lucca for the first time, and gets some advice from a friend who lives there. Arianna and Eleonora look at the map together to get an idea of how the city is laid out. With its Roman origins, Lucca's urban space was designed with intersecting roads called 'cardos' and 'decumani'.

Arianna takes us down to one of the most popular and busiest parts of the city. Many areas are primarily zone pedonali (pedestrian areas) but you still have to be very careful.

Today Arianna takes us back to Florence. This time we go to a high point on the southern side of the Arno river where we get a view of the whole city in all its splendor.

Arianna takes us down to a beach near Pisa, and explains a bit about how beaches work in many parts of Italy.

This beautiful church is worth a stop on the way from Pisa to the seaside. Arianna shares her discovery of it. The ceramic bowls that decorate the church are technically known as “bacini ceramici” in Italian, which could be translated as “ceramic basins.” Art historians who write in English, however, also use the term “bacini” for these tin-glazed works.

Arianna shows us around the Cathedral Square, where the bell tower, better known as the Leaning Tower of Pisa, is located.

Because Anna knows the subject backwards and forwards, she volunteers to take the teacher's quiz on Liguria, but that doesn't help much with her grade.

Gianni explores the interior of the abandoned villa, imagining what it might have been like before.

Gianni takes us up to an abandoned villa, and reflects on the tremendous challenges the builder faced.

The Region of the Marches, on the Adriatic coast of Italy, is lesser known than other regions, but there is lots to see here, with its long coastline and jewel-like cities.

Arianna shows us the outside market near San Lorenzo, and we discover where the train station got its long name Santa Maria Novella. Arianna also gives us some important information about how to get to and from the airports of Pisa and Florence.
