Arch of Janus, Tetrapylon at Forum Boarium, Rome, Italy.
Four massive marble pillars support intersecting vaults creating a square structure with passages measuring 12 meters on each side and rising 16 meters high.
Built during the fourth century AD near the Forum Boarium, this monument marked an important intersection between the commercial area and the river port.
Each arch contains niches that once held statues, with representations of Roman deities Roma, Juno, Ceres, and Minerva adorning the vault keystones.
The monument stands at the intersection of two main roads near the Velabrum district, where merchants conducted business and sought protection from sun and rain.
Medieval fortifications incorporated this tetrapylon as a defensive tower, which prevented its destruction and enabled its preservation through centuries.
