Passetto di Borgo

The Passetto di Borgo was an eight-hundred metre long elevated walkway through the centre of Rome, that connected Sinstine Chapel with the Castel Sant'Angelo. In 1499, the Assassin Ezio Auditore da Firenze fought his way along the Passetto di Borgo in order to get to Pope Alexander VI – Rodrigo Borgia.

 * In Assassin's Creed II, the Passetto di Borgo is significantly larger, looking much more like a city wall then the raised walkway it is in reality.
