Orvieto is located on a site that rises above volcanic tuff cliffs. Moreover, Orvieto has been fortified by large walls which are themselves made of the volcanic stone called Tufa. One of the most interesting facts about Orvieto is that is has an underground city which has existed for years, perhaps centuries. While archaeological excavations are still on, they all point to the fact that there has been a very well entrenched city which existed below the existing commune of Orvieto where there have been stairs, cellars, galleries, tunnels among others. It is believed that these tunnels were meant for noble families to escape the city in case of a siege. Because of its location, its Etruscan roots, charming medieval character, and its celebrated Cathedral of Gothic architecture, Orvieto is one of Italy's most unique and interesting cities.
