Alberto Angela talks about how Akragas came to be, how its name changed over time, and about what information has been obtained from archeological digs.

The temple dedicated to Concordia was built on an ancient seabed from two million years ago, and is one of the most remarkable structures from the Greek world. Alberto Angela explains why it is the only one still standing.

We're in the south of Italy, where many cultures have merged. Alberto Angela takes us to visit the magnificent Valley of the Temples in Agrigento, Sicily.

There is more to tell about the incredible, huge cistern in the center of Matera. With this, the episode concludes, with an invitation to join in the next journey of discovery.

In Matera, various epochs shake hands, as Alberto Angela put it. Matera continues to amaze us with what's hidden underneath the piazza of the Baroque quarter: Il Piano.

Living conditions were so different at the time of the cave dwellings. Imagine having a mule and rabbits running around the house! The government eventually put a stop to this type of dwelling, and much was gained, but much was lost. On the other hand, people had to live somewhere. The Civita, the oldest part of Matera, filled up quickly around the imposing cathedral, and there was no more room for building houses.

We see the inside of house built into the rock. It is fascinating to learn how families coped with the problems of water, humidity, and cramped quarters.

We enter a fascinating church carved right into the rock: the Church of the Madonna di Idris. There are some surprising discoveries awaiting us.

Matera is all about caves and grottoes. There were many natural caves that were expanded to be used as dwellings and churches, and other man-made grottoes as well.

Alberto Angela us takes back in time, to a city that came about in a totally different way: splendid Matera in Basilicata. It's definitely worth a trip.

We leave the Royal Palace of Caserta and head towards Cilento in Campania where there is a huge Benedictine monastery. When we see the term convento, we might assume it is a convent for nuns, but in Italian, un convento can be a religious community for either monks or nuns (or both).

Exploring the gardens further, we come upon a grotto, as well as what looks like an ancient Roman site, replete with original statues. It was all part of Vanvitelli's plan.

If we thought the interior of the Royal Palace of Caserta was amazing, we should get ready for even more amazement as we go outside and see the spectacular park — a true capolavoro (masterpiece) — which Luigi Vanvitelli, architect and engineer, designed, giving water the starring role.

The narrator makes us aware of the vast number of people necessary to run the Palace. We visit the most intimate place in the Palace: the queen's dressing room and bathroom. It is fascinating to learn all the ways in which it was outfitted to both pamper and protect the queen.

Alberto Angela takes us from the public throne room to the private chambers of the Royal Palace. In order to obtain the desired wall coverings, a whole complex was built for manufacturing silk. It's still operating today. Incredibile!
