In May 2001, an exciting discovery was made by Advanced Digital Communications (ADC), a Canadian company that was mapping the ocean bottom of Cuba's territorial waters. Sonar readings revealed something unexpected and quite amazing 2,200 feet down: stones laid out in a geometric pattern that looked very much like the ruins of a city. "What we have here is a mystery," said Paul Weinzweig, of ADC. "Nature couldn't have built anything so symmetrical. This isn't natural, but we don't know what it is." A great sunken city? It must be Atlantis, was the immediate suggestion of many enthusiasts. National Geographic showed a great deal of interest in the site and was involved in subsequent investigations. In 2003, a minisub dove down to explore the structures. Paulina Zelitsky of ADC said they saw a structure that "looks like it could have been a large urban center. However, it would be totally irresponsible to say what it was before we have evidence." Further explorations are forthcoming.More information: Probe Into Cuba's Possible Sunken City Advances
