The Arch of Constantine is probably the most renowned Roman triumphal arch. It was erected in 313 AD to celebrate emperor Constantine triumph over Maxentius and it is situated nearby the Coliseum, where old Via Sacra used to be. The arch is approximately 25 metre high and has three archways, with a larger central archway and two minor lateral ones. It was built with materials coming from the ruins of previous monuments in a difficult period for Rome, when the upcoming decline was at the horizon. The Arch decorations and statues depict Rome history and include scenes from Constantine and Marcus Aurelius battles.
