Rocca Paolina, corridor of the interior

Built between 1540 and 1543, the Rocca Paolina fortress was originally divided into three parts: the papal palace, the corridor and the tenaglia. After destruction in 1848 and almost complete demolition in the years after 1860, only the lower sections of the papal palace survived, which were uncovered and made accessible to the public between 1932 and 1965.
