What if the Romans had also invented the subway? Then there’s no doubt their road network would have been more like a giant subway system all across Europe. With this idea in mind, designer Sasha Trubetskoy researched and created subway-style diagram of the major Roman roads, based on the Empire of ca. 125 AD.

He admits the process took longer than what he expected, as “there is not a single consistent source that was particularly good” for this, but the result is definitely worth it. “The lines are a combination of actual, named roads (like the Via Appia or Via Militaris) as well as roads that do not have a known historic name (in which case I creatively invented some names),” he explains, confessing he took some creative liberties (you can check them out here).
