• IN PICTURES: City Beneath the Waves: Pavlopetri

A submerged ancient Greek city, from the heroic era portrayed in Homer’s Iliad, is being ‘raised’ from the bottom of the Aegean.

Using cutting edge underwater survey equipment and site reconstruction software, archaeologists and computer scientists have joined forces to map and digitally recreate a Bronze Age port which was swallowed by the waves up to 3000 years ago.

It’s the first time that a submerged city has ever been fully mapped in photo-realistic 3D.

The entire city – covering 20 acres – has been surveyed in ultra-high definition, with error margins of less than three centimetres.

The survey – carried out by an archaeological team from the University of Nottingham – is the subject of a special BBC Two documentary, tomorrow Sunday evening.

The original name and political status of the site is a complete mystery. The evidence so far suggests that it flourished between 2000 and 1100 BC, peaking in size in the two century period, 1700-1500BC, and being abandoned about a century before the end of the millennium.
