The Signorino road, of Etruscan origin, is a deep underground passage carved into the tuff that connects the Signorino district (named after a 15th-century family) to Porta Faul. It winds between high tuff walls that reach 12 meters at their highest points. It is also known as Cava S. Antonio (St. Anthony's Cave) after a shrine dedicated to the saint located on one of its walls. Along the road there is a cave called the Devil 's Cave , and some legends tell of strange nocturnal processions of Lucumoni (ancient Etruscan priests). For this reason, especially during the Middle Ages, crosses were carved on the tuff walls to protect travelers from the devil. The shrine dedicated to St. Anthony may have served this purpose.

The Teatro dell'Unione was built at the behest of a group of notable citizens of Viterbo who, led by Count Tommaso Fani Ciotti, joined together in 1844, with a deed of incorporation, to form the “Società dei Palchettisti”: the theatre took its name from their “union”. The Teatro dell'Unione was built because of the great interest the people of Viterbo had in opera, of which they were refined connoisseurs. The Società dei Palchettisti undertook the construction of this building with the intention of creating a "temple" dedicated to opera, given the presence of another theater in the city, the Genio. Even today, the Teatro dell'Unione is one of the most beautiful 19th-century Italian-style theatres in Lazio. During the Second World War, bombings, which devastated the entire city, also damaged the theater: the explosion of the bomb that hit the eastern section, where the dressing rooms were located, damaged the frescoes in the foyer , the box office, and a portion of the fresco in the auditorium. To access the funds earmarked for post -war reconstruction , the heirs of the notable Viterbo citizens who built it decided to sell the building to the municipality, which has owned it ever since. With the arrival of funds, the Municipality took care of the restoration and the theatre was reopened in September 1952. The Teatro dell'Unione remains, to this day, undisputedly one of Viterbo's architectural jewels.

Porta Fiorentina is one of the ancient gateways to the city of Viterbo, located along the medieval walls surrounding the historic center. It represents one of the main entrances to the city and opens northward, towards the Via Cassia and the city of Florence, from which it takes its name. The construction of the Porta Fiorentina, originally known as Porta Santa Luci, dates back to the 13th century, during a period of intense urban fortification that saw the expansion and strengthening of Viterbo's city walls. The gate was built to control trade and military flows from the north and represented a strategic access point to the city. It was rebuilt in 1768 under Clement XIII and subsequently enlarged in 1886–87 to adapt it to the growing need for urban traffic. It has three arched openings: a central round arch, wider for vehicular traffic, flanked by two smaller round arches, intended for pedestrians or secondary traffic. The arches rest on pillars or columns with capitals – originally in Corinthian style – which introduce a neoclassical ornamental component.

The Rocca Albornoz was built in the 14th century by order of Cardinal Egidio Albornoz, with the aim of reestablishing papal authority over the territories of the Papal States. Conceived as a military fortress, it features a massive tuff structure, with towers and defensive structures dominating the surrounding area. Its strategic location allowed for control of access to the city, particularly along the Porta Fiorentina route. More than a residence, the Rocca was a clear symbol of political and military power. Today, the building is a museum, housing the National Etruscan Museum of Viterbo, which has restored its spaces to a cultural function.

Piazza della Rocca is a charming corner of Viterbo's historic center, dominated by the massive Rocca Albornoz, built in the 14th century as a papal military garrison. On the opposite side is Porta Fiorentina, an ancient gateway to the city, a reminder of Viterbo's strategic importance in the Middle Ages. At the center of the square stands a fountain, once essential for water supply and now a scenic feature. The ensemble of buildings and tuff walls gives the square a highly scenic appearance.

Piazza di Santa Maria in Poggio is a small, quiet, and intimate medieval square, nestled slightly elevated in the heart of historic Viterbo. Far from the busiest streets, it retains an intimate and authentic character, deeply rooted in neighborhood life. The church that gives it its name, built in peperino stone, features a simple, austere façade, devoid of superfluous ornamentation, perfectly integrated into the surrounding urban fabric. It is a parish church, designed for a stable community, and it was here that Saint Rose of Viterbo was baptized in 1233, a sign of the profound connection between this place and the city's spiritual history. At the center of the square is a medieval fountain, also made of peperino stone, dating to the first half of the 13th century, created for the daily supply of water. Popular tradition links it to the young Saint Rose, who is said to have drawn water from here, adding a sense of memory and devotion to the place.
