Atlantis - a sunken civilization at the dawn of time. Greek philosopher Plato's descriptions from almost 2,500 years ago depict a utopia. A vast island empire with fascinating architecture and impressive military power. One night, however, the fabled empire is said to have perished in the wake of a devastating catastrophe. Scientists around the world are searching for traces of the sunken city. If it really did exist, there must be vestiges of this civilization just waiting to be discovered.
