Fortezza di San Leo

The origins of the fortress were already lost to memory at the time of the wars between Goths and Byzantines (sixth century). It was a constant subject of contention in the fourteenth and fifteenth centuries, until conquered by Federico da Montefeltro in 1441.

The fortress is a mighty defensive work designed by Francesco di Giorgio Martini and seems to be an extension of the rocky crag on which it stands, a work of both Man and Nature combined, with a majestic beauty all its own. Under the rule of the Papal State the fortress of San Leo became a harsh forbidding prison: Count Cagliostro ended his days in its cells. And even after the unification of Italy in the nineteenth century, the fortress continued to be used as a prison, up until the year 1906. Now a museum, the fortress has collections of armour and weaponry, and visitors can also see the cells of famous prisoners and the impressive fortifications.
