Alberto Angela tells us how these natural wonders were discovered by a group of young cave explorers from the nearby city of Ancona.

Alberto Angela brings us to the Ancona Abyss, an immense cave chamber in the Natural Regional Park of Gola della Rossa and Frasassi in the Marches region. The spectacular Ancona Abyss and other innermost caves in the Frasassi cave system were only discovered in 1971.

Nature offers us some extraordinary wonders, and this time, Alberto Angela takes us to the Frassassi Caves, in the Marches region, and explains what the caves were used for by prehistoric man.

As Mimmo and Franca enjoy the beach and swimming in the clear water, he tells her about his childhood in the town they can see from where they are sitting.

Carolina Raspanti plays Dafne, a girl of 35 who leads a regular life until she loses her mother and has to take care of her father suffering from depression. Dafne has Down syndrome, as does the actress who portrays her.

It was a tough 72 days, but, as the title suggests, the family recovered, luckily. They think back on their time in isolation and what it felt like to come out the other side. Their story even made it into a local newspaper.

If you have never been tested for Covid-19, Giuditta and Marino give a good description of the process. And their youngest son had to be very brave.

Coronavirus affects people in different ways. Marino and Giuditta share their experiences and recount what they did on their own, to try to get better.

Ancient culture merged with "modern" culture, especially after Constantine created the new capital of the Roman Empire, Constantinople. Near Matera in Basilicata, even caves built into the rock face became churches. The frescoes on those walls are quite stunning.

If you have ever visited Italy, you have probably run across the term pinacoteca describing a picture gallery, and wondered where it came from. You will find out in this video about a room called the "tablinum" in the Assisi domus, discovered because they wanted to build an elevator!

Parking is a problem in medieval hilltop towns and cities (especially those attractive to tourists), so one solution is to build an elevator to get from parking further down the hill, up to the center of town. But, you never know what you are going to find when excavating. In Assisi, they certainly hit the jackpot, right in the center of town: A roman domus.

We're in Assisi, where, during some excavations, a domus was discovered. It's clear it belonged to a wealthy family because of the richness of the wall and floor decorations, and might even have been the home of the poet Propertius.

With a look at one of the greatest Etruscan masterpieces in the Villa Giulia museum, we take our leave of Rome to journey to the Umbrian city of Assisi, or, as it was called in Roman times, Assisium.

Horses are large animals, but they are delicate, too. Keeping them healthy and in good condition requires a series of essential measures of different kinds. Eleonora takes us through some of them.

The Etruscans were influenced by other ethnic groups, particularly the Greeks. On display in the National Etruscan Museum of Villa Giulia, we find evidence of this in the terracotta objects and fine gold jewelry and precious objects dating from the period.
