There is a legend about the Dolomites, which has to do with a famous rose garden.

Alberto Angela gives us a simplified but fascinating description of how the Alps, and the Dolomites in particular, were formed from the sea. He goes on to tell a completely different story involving the Dolomites.

We finally learn where the name "Dolomites" comes from. We also learn the fascinating story of how these mountains came to be.

Alberto Angela explains how these wooden boards of red spruce become important parts of stringed instruments. The Dolomites are also a very unique place in terms of the land itself and how it is managed by the people who live there.

Alberto Angela takes us to the place where the best wood for making stringed instruments can be found: the Paneveggio Forest.

Alberto Angela takes us to some of the most beautiful mountains in the world, the Dolomites. How did they become so popular? It's a fascinating story.

We discover an amazing spot in the Italian Alps that overlooks the Chisone valley: an eighteenth-century fortified boundary wall, one of the longest in the world.

The Grinzane Castle houses a Museum of Peasant Civilization. Alberto Angela shows us a huge wine press and explains how it worked.

This segment is about how the famous wine Barolo came into being. It all started in the Grinzane Castle in the mid-1800s.

We go to the northern part of Italy: Piedmont, and here, in the southern part of the region, called le Langhe, what's worthy of being a World Heritage Site is about the land itself and what it produces, rather than about art and architecture.

There are a lot of interesting places to see from the walls, as Arianna rides around on her rental bike: the botanical garden, a tower with trees on it, and the entrance to a pilgrimage route to Rome.

The final segment of this tour of Umbria and Tuscany brings to the walls of Pisa and its famous schools of higher learning. As usual, Alberto Angela gives us some insight into how and why things happened as they did, as Pisa developed into one of the most beautiful and important cities in Italy.

The fresco depicting the Last Judgement is almost like a photograph of the Middle Ages. Alberto Angela shows us where the sinners ended up and what happened to them in Hell.

The best way to get around Lucca is by bike. Arianna rents one and enjoys riding along the amazing walls of the city, still intact after centuries.

We're still at the Camposanto in Pisa. Alberto Angela shows us a wonderful fresco of the Last Judgment, and tells us the story of the artist as well as what is depicted.
