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.

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.

Imagine being on vacation and having to fly home during the pandemic. That's what happened to Melania who got stuck in Madrid on her way home from Venezuela.

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

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.

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.

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