Is this Atlantis?

It was hard to write that headline. I never took Atlantis seriously. The ONLY historical source was the two dialogues by Plato, who never even claimed he was reporting actual history.
But here we are in Spain, using advanced technology to map sites of circular communities that at least resemble the classical description, although far smaller. Were they built by people who remembered Atlantis after a tsunami inundated the original site? That's one idea.
