This map was published by Joe Davies in 2020 as part of the initiative #30DayMapChallenge.
The Roman Empire's road network is one of the most impressive achievements of Roman engineering. This map shows the roads that existed in the empire at its peak. As the author notes in the upper right-hand corner, according to the available data compiled by a Harvard study led by Michael McCormick.
As the author notes in the upper right corner, the Roman Empire built more than 400,000 kilometres of roads, 80,000 of which were paved. In total, the road network consisted of 372 main roads, which appear as thicker lines on the map, and other secondary roads, which appear as thinner lines.
In 2017, another popular map of the Roman Empire's road network was published, but on that occasion as if it were a metro network.
