Porta Faul, Viterbo

Viterbo (Italian: [viˈtɛrbo] ; Viterbese: Veterbe; Medieval Latin: Viterbium) is a city and comune (municipality) in the Lazio region of Italy, the capital of the province of Viterbo. It conquered and absorbed the neighboring town of Ferento (see Ferentium) in its early history. It is approximately 80 kilometres (50 miles) north of GRA (Rome) on the Via Cassia, and it is surrounded by the Monti Cimini and Monti Volsini. The historic center is surrounded by the medieval walls of Viterbo, which are still mainly intact, built during the 11th and 12th centuries. Entrance to the walled center of the city is through ancient gates. Apart from agriculture, Viterbo's main resources are pottery, peperino stone, and wood. The town is home to the Italian gold reserves, an important Academy of Fine Arts, the University of Tuscia, and the Italian Army's Aviation Command headquarters and training centre. It is located in a wide thermal area, attracting many tourists from all over central Italy.

Viterbo Cathedral (Italian: Duomo di Viterbo, or Cattedrale di San Lorenzo) is a Roman Catholic cathedral, and the principal church of the city of Viterbo, Lazio, central Italy. It is the seat of the Bishop of Viterbo and is dedicated to Saint Lawrence. The church is an imposing Romanesque structure situated high on the hill which the city climbs, but it lacks much of the spectacular decoration with which it was originally adorned, thanks to an ill-advised sixteenth-century reconstruction.

Palace of the Popes in Viterbo (Italian: Palazzo dei Papi) is a palace in Viterbo, region of Lazio, Italy. It is considered to be one of the most important monuments in the city, situated alongside the Duomo di Viterbo (Viterbo Cathedral). The Papal Curia was moved to Viterbo in 1257 by Alexander IV, due to the hostility of the Roman commune and constant urban violence: the former bishop's palace of Viterbo was enlarged to provide the Popes with an adequate residence. The construction, commissioned by the Capitano del popolo ("Captain of the People") Raniero Gatti, provided a great audience hall communicating with a loggia raised on a barrel vault above the city street. It was completed probably around 1266. The massive façade, facing the central piazza San Lorenzo which is dominated by the Duomo, is approached by a wide staircase completed in 1267. The top of the palace walls is decorated with square merlons. On the right is a wide roofless loggia with a seven-bay arcade, supported by slender doubled columns and decorated with crests and reliefs. Within the loggia is a 15th-century fountain, made with material of various ages, sporting the coat of arms of the Gatti family. Viterbo remained the residence of the papacy for twenty-four years, from 1257 to 1281. After Alexander IV, the palace was the residence of Urban IV, then housed the papal election of 1268–1271 which elected Gregory X (the longest papal election in Church history, which ended after the palace's roof was removed), the residence of John XXI (who died in the building in 1277 when his study collapsed), and the residence again of Nicholas III and Martin IV, who moved almost immediately to Orvieto in 1281. They were all elected in the most famous hall of the palace, the Sala del Conclave so called because it was home to the first and longest conclave in history. In c. 1454 Pope Nicholas V commissioned building a bath palace in Viterbo, and the construction at the Bagno del Papa was continued on through the reigns of several popes after Nicholas V. The Vatican accounts mention payments "for building done at the bath palace of Viterbo" during the reigns of Calixtus III, Paul II, and Sixtus IV. There also is evidence Pope Pius II was responsible for the addition of a western wing to the building.

A fountain at this site, in front of the Jesuit church, now known as San Silvestro is mentioned for the first time in public documents in 1450. After centuries of litigation related to the flow of water, in the year 1727 the fountain was purchased by the Chigi family, they commissioned the repair of the tank and pipes in 1806. By 1915, it was decided to replace the fountain with a new structure made utilizing spolia from the fountain of the convent of San Domenico. A design by Giovanni Pizzichetti was selected. The lower basin is decorated with lion heads (symbol of Viterbo); while the upper basin stands on a tree decorated with alternating lion heads, oxen, horses and sheep.
