Which mountain range separated Roman territories from Germany?

The Alps are the mountain range that effectively separated Roman territories from Germany. This range stretches across several European countries, including France, Switzerland, Italy, and Austria, serving as a significant geographic barrier. During the height of the Roman Empire, the Alps provided a natural defense against incursions from tribes in what is now Germany.

The strategic importance of the Alps was recognized by the Romans, as they not only protected the Empire's northern borders but also allowed for controlled trade and movement between regions. The Romans constructed roads through the Alps to facilitate their military and economic activities, emphasizing the range's role in dividing their territory from neighboring lands.

While the other mountain ranges mentioned have their own geographic and historical significance, they do not play the same role in separating Roman territories from Germany. The Pyrenees separate Spain from France, the Carpathians lie further east in Central Europe, and the Apennines run down the length of Italy. None of these ranges served as the boundary that demarcated the Roman influence from the territories to the north, like the Alps did.
