Documentary brings world's oldest underwater city back to life

Posted: 08 Oct 2011 10:03 AM PDT

Movie industry computer graphics and the very latest digital marine technology have brought the world's oldest submerged city back to life in a new documentary. Just a few metres under the sea, off the southern coast of Greece, lies Pavlopetri -- the oldest submerged city in the world. A team of archaeologists has spent the last three years surveying the site which was first discovered in the late 1960's. This summer the city, which dates back over 5,000 years, became the first underwater city to be fully digitally mapped and recorded creating a highly detailed stone by stone plan in photo-realistic 3-D.
