San Leo, the historical capital of the Duchy of Montefeltro, is a small village that will leave you open-mouthed at the very first sight. It is perched on a rocky spur, a natural fortress that has been a fundamental strategic defensive post over the centuries. The fortress still towers over the whole area, imposing and invincible with its fortified towers and its parade ground. A story written in stone that tells about the past and accompanies visitors in a trip through the events and atmosphere of local history. Here is where the famous Count Cagliostro lived, the adventurer, esotericist and alchemist condemned to life imprisonment in the Fortress for heresy by the Catholic Church.
