What remains of Porta Salaria along the Aurelian Wall is located in Piazza Fiume. The gate is historically significant. This is where the Visigoth troops of King Alaric entered the city in 410 AD. The military action is called the Siege of Rome. For three days, they looted valuables from major landmarks and citizens. Porta Salaria was also where Vitiges, the king of the Ostrogoths, attacked in 537.
