Arco di Giano
Via del Velabro
+39 06 0608 (Tourist Information)
The last standing four-fronted arch in Rome, Arco di Giano is a must-see for those on a quest to explore the Eternal City. Not hard to find, this monument sits on the edge of the Forum Boarium and Velabrum junction near the Church of San Giorgio al Velabro and Arch of Argentarii. The origin of this magnificent structure can be traced back to early 4th century, believed to be built in the time of Constantine I and Constantius II. The four pillars once bore crowns that were removed by the Frangipane family in the Middle Ages, to convert the structure into a fortress. Although not confirmed, the arch is possibly dedicated to the ancient Latin God Janus - the four pillars depicting the four-faced version of Janus.
