It was set up in the early 4th century AD at a crossroads at the northeastern limit of the Forum Boarium, close to the Velabrum, over the Cloaca Maxima drain that went from the Forum to the River Tiber.
The location of this structure dates back to the early 4th century AD, situated at a junction near the Forum Boarium's northern boundary, adjacent to the Velabrum and the Cloaca Maxima sewer system which directed waste from the Forum towards the Tiber River.
