Rome's last and largest triumphal arch was dedicated near the Colosseum in A.D. 315 to celebrate Constantine's victory three years earlier over Rome's Western Emperor Maxentius.
Seen in the Rome Reborn simulation circa A.D. 320, the brilliant white marble arch is decorated with colored stone panels and a variety of sculptures taken from previous monuments.
A fountain called the Meta Sudans, built sometime between A.D. 70 and 90, sits across from the arch.
