Via Flaminia
The previous name was "Porta Flaminia", because the consular Via Flaminia passed, as it passes even now, through it (in ancient times, "Via Flaminia" started at the Porta Fontinalis, close to the current Vittoriano). In the 10th century the gate was named "Porta San Valentino", due to the basilica and the catacomb with the same name, rising at the beginning of Viale Pilsudski.
