“Roman Roads” by Sasha Trubetskoy: a subway-style diagram of the major Roman roads, based on the Empire of ca. 125 AD.
Based on the map produced by this designer, I focused on the Alpine region in order to highlight them. Of course, the decisions Trubetskoy has an influence (“here is no way I could include every Roman road, these are only the main ones. I tried to include cities with larger populations, or cities that were provincial capitals around the 2nd century.”) but it’s interesting to look at which Alpine cities were important at the time. See how Augusta Prætoria Salassorum (Aoste, IT), Vapincum (Gap, FR), Aventicum (Avenche, CH), Curia (Coire, CH) are present here, while Turicum (Zürich) is not.
