This is Corinth, which was, of course, an ancient Greek city, but in its excavated form mostly goes back to the period after the Roman foundation of a colony: the Greek city was smashed to pieces by the Roman army in 146 BC. The excavations have mainly focused on the forum but they have included the first meters of the road connecting the city to its harbour at Lechaion. As you can see, this was a beautifully paved street, ending in a staircase. It does not have wheelruts, so perhaps, wheeled traffic was entirely kept away from it. The buildings around the street were as monumental as the street itself, and it shows how, in the Roman period, even cities in the provinces could become rather densely monumentalized.
