The Commune of St. Venanzo, among Umbria's biggest as far as territory is concerned, but among those with less population, is mostly situated on the slopes of Mount Peglia (800 metres above sea level), between the Tiber valley and Orvieto.

Seat of Mount Peglia and the Selva di Meana mountain community, present an almost entirely intact territory, where a population well below 3000 is scattered among tiny villages, such as San Vito in Monte, Poggio Aquilone, Civitella dei Conti, Collelungo, Palazzo Bovarino, Spante, Pornello, San Marino, Ospedaletto, Ripalvella.

Among these, Rotecastello, with its medieval tower and its spectacular position, is one of the most fascinating.
