Arch of Janus

Rome, Italy

It is the only preserved four-sided arch (tetrapylon) in Rome, unique among structures like the Colosseo or Colonna di Traiano.

The Arco di Giano is an ancient Roman triumphal arch from the 4th century CE, located in the Forum Boarium in Rome. It is the only preserved four-faced arch (tetrapylon) in Rome. Built from salvaged materials, mainly marble, it probably served an honorary function or as a shelter for traders. It measures about 16 meters in height and is adorned with niches that once housed statues of deities. This arch was an urban element of the ancient river port.
