Our journey takes us to the region of Campania, and to Naples, where we visit one of the oldest theaters still functioning: il Teatro San Carlo.

In the eighteenth centiury, the San Carlo Theater was a magnificent center for opera and culture, and still is today. It's one of the most beautiful theaters in all of Europe.

The Teatro San Carlo was renowned in all of Europe for its beauty as well as for its music, theater, and opera productions, so when it caught fire in 1816, it was a major tragedy. King Ferdinand I had it rebuilt immediately, and it became even more magnificent than before.

The San Carlo Theater was the largest in Europe. Alberto Angela focuses on the shape of the theater and provides some insight into what went on in the box seats.

Alberto Angela continues showing us some of the details of the decorations within the San Carlo Theater. He recounts a special coffee beverage invented there, and an anecdote about the composer Gioacchino Rossini who was the musical director there for a time.

Gioachino Rossini had great success as an opera composer at the San Carlo Theater in Naples, writing a large number of operas while still quite young. When he left Naples for Paris, he was replaced by another star composer, Gaetano Donizetti.

Bel canto (beautiful singing) and lyric opera began in Italy, and, not surprisingly, this country has the highest number of opera theaters in the world. Thus we conclude this episode of Meraviglie (wonders).

In this episode, we travel to Lecce, to the very heel of the Italian "boot," at the southernmost tip of the Italian peninsula. Lecce is an iconic example of the Italian Baroque, which encompassed music, art, literature, and philosophy.

What's so special about Lecce? It has something to do with the kind of stone found there. And masters of art and architecture knew how to make beautiful buildings with it, giving rise to the Lecce Baroque.

Visiting Piazza Falconieri makes you feel as if you were in a fairytale. The stone used for these beautiful buildings and decorations has a particularly interesting story.

In addition to its Baroque art and architecture, Lecce has a rich ancient history, underscored by a Roman amphitheater, in part still standing, right in the middle of the city. But Lecce's history goes even further back than that.

We visit a famous monastery near Lecce, which got its name from the Olivetan monks who lived there. They had come from another famous monastery in the province of Siena, the Abbey of Monte Oliveto Maggiore. Alberto Angela describes the symbolism of the beautiful, mid-sixteenth century canopy well in the cloister. Today, the monastery houses the University of Salento.

The monastery boasts a beautiful, wide staircase from the first half of the 18th century, with some curious charcoal drawings whose purpose remains a mystery. The monastery went through several transformations before becoming what it is today, the seat of the University of Salento.

We're back in the center of Lecce, where there's one of the most beautiful piazzas in Italy, the Piazza Duomo (cathedral square). It can be described as theatrical and eye-poppingly stunning, but it also had an important practical function in its past.

In 1693, there was a terrible earthquake in the south-eastern part of Sicily, and much of it was razed to the ground. The subsequent rebuilding of the cities followed the tenets of the Baroque style that had already taken hold during the Spanish reign.
