We move from the lower basilica to the upper one, which has an entirely different feel to it. Here, we are surrounded by a show of light and color in colorful frescoes and stained-glass windows.

Alberto Angela points out how realistic Giotto's frescoes are compared to earlier ones. He also mentions the important fact that Saint Francis composed one of the first poems in the vernacular

Everyone is talking about coronavirus. Marika addresses frequently asked questions about this recent, ongoing phenomenon.

Marika talks about how one can contract coronavirus, the symptoms, and the guidelines to avoid getting infected.

We move from Umbria to Tuscany and visit the evocative ruins of the abbey of San Galgano. Next will be Pisa, a prime example of how Tuscany, in medieval times, was experimenting with very "modern" ideas.

Alberto Angela gives us a look at one of the most famous monuments in the world. We look at the Leaning Tower of Pisa through the lens of those who wanted it built.

Why does the Leaning Tower of Pisa lean? Alberto answers this question and others about one of the most famous monuments in the world.

We go inside the Pisa Cathedral and see how marvelous it is, from the granite columns to the majestic pulpit designed by Giovanni Pisano, which, miraculously, survived the fire of 1595.

We learn a great deal about the third structure at the Piazza dei Miracoli in Pisa: the Baptistery. We learn about wonders we can see and wonders we can't see.

Alberto Angela recounts some interesting facts and legends surrounding the roof of the Bapistery and the Camposanto [cemetery].

Alberto Angela takes us through what is actually a gallery of ancient art inside this cemetery, and focuses on the sarcophagi, each with its story to tell.

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.

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 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.

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.

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

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

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.

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.

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

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.

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

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.

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