What is Viterbo known for?

Five popes elected in Viterbo between 1257 and 1281; the 1268-1271 conclave was the longest in Church history and gave the word its meaning. Five-ton thirty-meter illuminated tower carried through the streets on 3 September by a hundred Facchini, UNESCO listed since 2013. Sulfur thermal complex used since Etruscan times and rebuilt under the popes, still the largest bathing pool in central Italy.

Viterbo is a comune in the province of Viterbo, Lazio region of Italy, about 60 kilometers from Terni.

Why come

Viterbo sitsin the Tuscia, surrounded by the volcanic Cimini hills and the thermal springs the Etruscans and Romans already used. The city became the favourite papal residence under Eugene III in the twelfth century; between 1257 and 1281, five popes were elected here, and the conclave of 1268-1271 ran nearly three years, the longest in Church history. To end it, the city's people locked the cardinals inside the Palazzo dei Papi, tore the roof off, and reduced their rations. The decisive conclave is still the reason the word means a place under lock and key. The San Pellegrino quarter is the largest continuous medieval district in central Italy, with profferli, the external stone staircases that climb to first-floor doorways. The Terme dei Papi outside the walls still draws sulfur-water bathers. On 3 September the Macchina di Santa Rosa, a thirty-meter illuminated tower weighing five tons, is carried through the streets by a hundred Facchini, a tradition listed by UNESCO since 2013.

Viterbo works as a year-round destination because of the thermal springs. April through June and September into October give the easiest combination of clear weather, open monuments and warm pool water. July and August push the medieval quarter into the mid-thirties; the Macchina di Santa Rosa on 3 September is the single largest event in the calendar and the streets stay packed for the night. November through March is the season for the Terme dei Papi, when the hot sulfur water steams above the cold air and the San Pellegrino quarter empties to almost no one between visits.
