Historical Background

Remnants of 14 Roman bath buildings can be found throughout the area, with Aquae Passeris, Paliano, and Bullicame being the most significant. These thermal springs have been mentioned by well-known figures such as Vitruvio, Strabone, Tibullo, Simmaco, Marziale, and Scribonio Largo, physician to the emperor Tiberio.

One of the most remarkable thermal structures in Viterbo is “Il bagno del Papa,” a personal thermal retreat built by Pope Niccolò V in 1450. Designed by the famous architect Bernardo Rossellino, this beautifully decorated building was later modernized by Pope Pio II. The influence of Viterbo’s thermal springs can even be found in Dante Alighieri’s Divine Comedy, where he mentions them seven times. A popular verse from the poem is carved in a stone pillar next to the Bullicame spring, which is a must-visit attraction.

In addition to the thermal baths, Viterbo boasts a wealth of historical buildings and cultural attractions. The Museo Colle del Duomo, Palazzo dei Priori, Museo del Sodalizio dei Facchini di Santa Rosa, Museo Civico Rossi Danielli, Museo Nazionale Etrusco Rocca Albornoz, and Museo della Ceramica della Tuscia are just a few examples of the heritage sites waiting to be explored.

Nature lovers will also find solace in Viterbo. The Riserva Naturale Lago di Vico, established in 1982, is a protected area that showcases the beauty of the ancient forest of Monti Cimini. This natural heritage site was recognized by UNESCO on July 7, 2017, further highlighting the importance of preserving its unique ecosystem.
