Nepi is a municipality in the province of Viterbo. The municipal territory extends over the Agro Falisco, bordered to the south and south-west by the Sabatini Mountains, to the north-west by the Cimini Mountains and by the Tiber Valley to the north and east. The “Forre”, a characteristic geomorphological element of the territory, are large valleys delimited by sub-vertical walls excavated by the millenary erosive action of the streams on the volcanic substratum: they were inhabited since Prehistory, as discovered thanks to archaeological finds. From an architectural point of view, there are numerous churches, the Rocca dei Borgia, the town hall, the eighteenth century aqueduct and numerous other palaces. What makes the village of Nepi very elegant are the numerous medieval towers. There are also various archaeological sites including: the Catacomb of Santa Savinilla, a late imperial cemetery complex, the Vie Cave, ancient paths from the Faliscan era, and the Tre Ponti necropolis, a small complex of rock tombs with porticoes.
