Mexcaltitán is a small inhabited island in North West Mexico that is laid out with concentric streets intersected by two perpendicular avenues(a). Some locals compared its layout to that of old maps of Tenochtitlán the legendary capital of the Aztecs, which in turn has been proposed as having a connection with Atlantis. The idea is totally fanciful and does not stand up to the most cursory examination.

Paul Aucler (1865-1915) was a French archaeologist who published a reconstruction of ancient Carthage in 1899. The layout he presented has been commented on for its similarity with Plato’s description of the capital city of Atlantis.
Robert Stacy-Judd, a prominent diffusionist, was one such commentator, who was not suggesting that Carthage was the location of Atlantis, but when a similar layout was to be found at Tenochtitlan (Mexico City) and elsewhere, it, according to him, seemed to imply a common source of inspiration – Atlantis!
Tenochtitlán was the capital city of the Aztec empire, occupying what is now the centre of Mexico city, in what we know as the Valley of Mexico. At the time of the Spanish invasion in 1521 it has been estimated that its population numbered over 200,000, making it one of the largest cities in the world at the time. It was built on an island in the middle of a lake(a), a feature often found with many ancient Aztec towns and cities.
The features of Tenochtitlán have been frequently compared with Venice and its canal system, not to mention the concentric waterways of Atlantis described by Plato. Like Atlantis, it too has its central pyramidal temples as well as bridges and other structures.
Edward Ziomek continues to promote the idea of a Mexican Atlantis centred on Tenochtitlán(b) and/or Teotihuacan(c).
