A city that thrived for 2000 years during the time that saw the birth of Western civilisation. An international team of experts uses the latest technology to investigate the site and digitally raise it from the seabed, to reveal the secrets of Pavlopetri.

More about this programme: http://www.bbc.co.uk/programmes/b015yh6f Pavlopetri was an advanced city whose origins are thought to have contributed to the 'dawning of the west'. More than 3500 years ago it functioned as an active harbour town with trading links around the Mediterranean, but was lost for centuries, under the waves. In this clip, the graphics team are able to build up a stunning portrait of how the city would have worked, following Dr. Jon Henderson's excavation of the site.
Through CGI we are able to rebuild and reimagine their large domestic dwellings, reconstruct many types of ornate vessels and containers, and revisit their forward thinking death rituals. The variety of discoveries reveal Pavlopetri to once have functioned as an impressive gateway to mainland Greece.

Here, team from the Australian Centre for Field Robotics take us through how they worked to solve the puzzle of the city, using an autonomous underwater vehicle, the first time such technology has been used on this scale on a submerged site.
Throughout the night, the camera took stereo images under the water to judge the distance between the ruins on the sea floor. The robot captured hundreds of thousands of images, in order to build up a 3D model - allowing the team to create views that would be otherwise impossible.
The graphics team carefully built up a 3D map from the layout of the ruins and the uncovered artefacts. The final images of Pavlopetri reveal an intricate portrait of the city around 1600 BC; a city at its advanced peak.
