Porta Pertusa, Historic gate at Viale Vaticano, Rome, Italy

Porta Pertusa is a walled-up gate in Rome's Leonine Wall, set on Viale Vaticano near the street of the same name. It has three openings: a main portal framed by rusticated stonework (bossage) and two smaller side entrances, all now closed with masonry. The gate stands beneath the tower of San Giovanni, the south-western bastion of the original Leonine Wall.

The gate was created during the late construction phase of the Leonine Wall after Popes returned from Avignon in the 14th century while the city was expanding. The additional passages became necessary to handle increased foot traffic and movement between the two territories.

The name comes from the Latin pertusus, "drilled", because the gate was cut through the existing wall. It was probably reserved for the Curia rather than ordinary town traffic. A 1655 document records that it was opened for the arrival in Rome of Queen Christina of Sweden.

The gate stands walled up on Viale Vaticano, near the street of the same name, beneath the tower of San Giovanni. It cannot be entered, so it is seen from the pavement outside. The 1655 document records that it was opened for the arrival of Queen Christina of Sweden.

During the French siege of Rome in 1849, French maps wrongly showed Porta Pertusa as open, so the army considered it a possible entry point, although it had been walled up years earlier. A 1655 document records that it was opened for the visit of Queen Christina of Sweden.
