Lost City: Atlantis

I believe there is one thing we can all agree on when it comes to Lost Cities, Atlantis is the poster child. Simply put, did it ever exist and if so, where?

We can thank Plato for kicking off this debate circa 360 BC, for he was the first to make recorded mention of the long lost seafaring superpower. It is a commonly held view that Atlantis was located in the Atlantic Ocean to the West of the Straights of Gibraltar. However some have found evidence that Atlantis may have been closer to Plato's Greek home.

So the questions. If, then where? And what of the lack of evidence from a formidable seafaring civilization? What say you? Discuss...
