Key
  • Certain Well documented, mapped to within about 50 to 200 m
  • Conjectured Known road, course less precisely documented
  • Hypothetical Route not pinned down, or existence uncertain
  • Secondary road Thinner line, any certainty

How accurate are these lines? Most Roman road routes on this map are approximate. The Itiner-e project, which supplies the data, classes most of them as Conjectured, so read a line as a best estimate of where the road ran rather than a surveyed route.

Roman roads in Portugal at a glance

Portugal has about 6,176 km of Roman road in the Itiner-e atlas, mapped as 239 segments. That puts it 14th among the 39 countries with Roman roads in the dataset. None of it is classed as certain: almost all of it is conjectured, so the line on the map is a best estimate of the course rather than a surveyed route. None of the roads here has a well-known name in the data, so the map shows unnamed Roman roads only. 57 Roman places (towns, forts, ports and stops) lie along the roads.
