Temple of Saturn
The Milliarium Aureum (; ), also known by the translation Golden Milestone, was a monument, probably of marble or gilded bronze, erected by the Emperor Caesar Augustus near the Temple of Saturn in the central Forum of Ancient Rome. All roads were considered to begin at this monument and all distances in the Roman Empire were measured relative to it. On it perhaps were listed all the major cities in the empire and distances to them, though the monument's precise location and inscription remain matters of debate among historians.
