The empire, where it is still standing up
Roman Europe
Rome's best surviving buildings are mostly not in Rome. They are in the provinces, where a later city did not need the stone, or where a cathedral was built inside the temple instead of on top of it. These are the places where the engineering is still doing its job.

Not an itinerary
A theme is a way of seeing, not a route: these places are not in travelling order and most people take three or four of them, not all. For an order that respects distance, put the ones you want into the Planner.
