The Porta Flaminia was a gate in the Aurelian Walls of Rome that opened directly into the Piazza del Popolo and therefore served as the northern entrance of the city. For its association with the Piazza del Popolo, it became known as the Porta del Popolo in modern times. Historically, it was the starting point of the Via Flaminia, one of Rome's most vital roads as it was the road north leading all the way to Ariminum.
- In Assassin's Creed: Brotherhood, all the gates of Rome are misidentified, but Shaun Hastings's database entries remain factually correct. The name "Porta Flaminia" is misapplied to the gate in the northeast corner of the Campagna District, in reality the Porta Salaria. In spite of this, the database entry on the Porta Flaminia correctly describes it as the gate granting immediate access to the Piazza del Popolo, even noting that it would later be renamed the Porta del Popolo. This gate before the Piazza del Popolo still features in the game, but it is incorrectly labeled the Porta Aurelia. For convenience, this article assumes that, canonically, Shaun Hastings's research is correct while the Animus 2.01 labeled the gates erroneously.
