Jaén is a large town north of Granada in Andalusia, Spain, which Georgeos Díaz-Montexano has claimed had an ancient configuration consisting of concentric rings similar to Plato’s description of Atlantis. He supports this idea with a dossier^(a) on the city and an illustration^(b) of pottery found in Jaén, now in the National Archaeological Museum in Madrid.
