Tower of Paul III (Rome)

The so-called Tower of Paul III (Torre di Paolo III) was a characteristic fortified villa belonging to the Popes, rising on the Capitoline Hill in Rome (Italy). The edifice was built in the 16th century by the architect Jacopo Meleghino at the behest of Pope Paul III and demolished in 1886 as part of the construction works of the Vittoriano. Its official name was Palazzo di Aracoeli, but it was also known as Rocca Paolina and Torre Paolina.
