I’ve been reading articles about this and that, including various Roman villas, towns, and necropolises in Iberia…which reminded me of our trip to Iberia early this year.
Here’s a reconstructed porticoed ambulacrum (one corner) that would have surrounded a forum square (depression, left foreground). This is the southwest corner of the Roman forum at Empúries, in far northeast Spain. There was a major trading city here under the Greeks, later built much larger by the Romans.
