Viterbo lived its period of major splendor and power in the 13th century when it was chosen as the seat of the papacy instead of Rome, where powerful warring families made life too dangerous. Eight different popes lived in Viterbo making it is similar to Vatican City and Avignon in France. The longest papal conclave in history happened here from 1 December 1268 to 1 September 1271. Following Pope Clement IV's death, infighting between cardinals and political pressure led to a 34-month deadlock. The cardinals were locked up cum clave (hence the word conclave) inside the palace’s large Conclave Hall. In desperation the town’s population, who were feeding them and their entourages, eventually reduced the cardinals’ food and wine supplies, trying to speed up the election. Time wore on and they finally decided to remove the roof of the palace: in order to help the Holy Spirit come down and illuminate them, it was quipped. That worked.

Okay, the Parco Thermale di Bagnaccio is once again open daily. In winter from 8am to 8pm, in Summer open until 23pm or even midnight! Entry is 5€ for pilgrims with credential (or if you are lucky like me, also without). Else it is 10€. There are three simple changing rooms, some toilets, a snack automat and coffee maschine and, sometimes just outside, a mobile little restaurant selling hot meals.

In the heart of Viterbo, Piazza delle Erbe owes its name to the vegetable market held there since the Middle Ages, when the square was a vital hub of city life. At its center is the Fountain of the Lions, built between 1621 and 1625, with its basin decorated with lions and marble coats of arms reminiscent of the city's coat of arms.
