Roman temple district on the Metzenberg
The Romans built a highway network for the military, commerce, administration and news delivery (cursus publicus). The highway passed by the Metzenberg to Marseille, Lyon, Toul, Metz and Trier. From Trier to Rome were around 1,800 kilometers, which the couriers mastered in just 7 days. Because the river valley was mostly marshy and often flooded, the roads were built on the ridges of the mountains. Trier was one of the Roman road junctions, from where the roads continued in all directions. On the way there were horse changing stations (Mutationes), rest, inns (Mansiones, Stabulae) and the Vici (Vicus) with craft trades, services and accommodation. The soldiers were housed in barracks. For the spiritual well-being of the locals and the guests the temples were built like these one.
