In late 2001, a Canadian research company, Advanced Digital Communications, discovered what seems to be a sunken city off the western coast of Cuba. The structures were found nearly 2000 feet below the surface and appear to be built more than 6000 years ago. The company submerged robotic exploratory equipment to film footage of the buildings. Research is still in progress today to learn more about Cuba’s own “Atlantis.” To learn more about the lost city, go here.
