Window in the “Pozzetto Cell,” the room that once held the adventurer and condemned heretic, Count Cagliostro, until his death in 1795. The cell originally had only entrance: a door in the ceiling through which guards lowered Cagliostro and his subsequent meals. The only other opening was this deep-set window with its multiple rows of bars, giving only a severely limited view of San Leo’s parish church, cathedral, and watchtower. Photo by Renée DeVoe Mertz.
