A massive cylindrical mile stone, over six feet in height and weighing two or more tons: "The miliaria were erected every 1,000 paces, or Roman mile, on all Roman roads after 123 B.C."

"The miliarium generally gave the distance from the town where the road originated, the name and titles of the emperor under whose auspices the road was built, sometimes the names of those who built it [Legio III Augusta build this road], and sometimes the date when it was finished."

"In addition, the miliarium generally specified whether the road was repaired (ristituit) or built at the emperor's own expense (pecunia sua) and whether it was a gravel road (via glarea) or a paved road (via stata)."

"Thousands of miliaria have been removed from the roads; many are found to have been used in building houses, churches, and foundations, while a few of the others have been moved to museums."

"In addition to milestones or miliaria, there were the itineraria to guide tourists, military commanders and commercial travelers over the Roman roads. The itineraria were schematic maps with symbols to indicate such geographical features as mountains, rivers, and lakes, as well as way-stops, official night quarters (mansiones), military bases (castra praetoriana), and post-houses, (mutationes) where horses were kept for use. The itineraria also gave the distances between points on the road."
