Mexcaltitán
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.
