Over 2, 200 years ago, a road was constructed from the Adriatic Sea into Rome. The terminus for Flaminian Way (Via Flaminia) and the city’s entrance was the gate on the left. The first version, Porta Flaminia, was built in 1475. It was renamed Porta del Popolo after reconstruction in 1565. Interestingly, the columns on the façade were salvaged from the Old St. Peter’s Basilica (built in 360 AD). Sharing the northern edge of Piazza del Popolo is Santa Maria del Popolo.
