The medieval fortress and the prison of Cagliostro
San Leo, a magnificent art capital mentioned by Dante Alighieri in the Divine Comedy, is the heart of the historical region of Montefeltro and the town that gave it its name. Famed for various historical and geopolitical events, it has been the location for documentaries and films, is a popular tourist destination and a jewel of the province of Rimini.
Its extraordinary geological configuration, on a rocky mass with sheer sides, has determined its dual military and religious importance since prehistorical times, testified by precious architectural and artistic artefacts. The town was once called Monte Feltro, from Mons Feretrus, a name linked to the important Roman settlement built around a temple dedicated to Jupiter Feretrius. As early as the 3rd century BC, the Romans built a fortification on its highest point.
The early Christian period (2nd century AD) was characterized by its evangelization following the arrival of Leo and Marino, two Dalmatian stonecutters who founded the Christian communities of San Leo and San Marino thus favouring the spread of Christianity throughout the area until the foundation of the diocese of Montefeltro.
