Pavlopetri, a Bronze Age hellenist town, now underwater, was extensively re-surveyed recently:

With shafts of sunlight shimmering through a few metres of crystal clear water, you can pick out the cornerstones of an ancient civilisation which inspired literature and legend.
There is more than a whiff of Atlantis about the story of Pavlopetri - the world's oldest submerged town.
But the Bronze Age site, off the coast of Laconia in Greece, has its roots in fact not fiction.
New underwater archaeology techniques - with sonar mapping used by the military and off-shore oil industry - are giving up new secrets.
An international team, given special permission to dive by the Greek government, has found artefacts on the sea bed dating back 5,000 years.
This fresh information puts the world's oldest submerged town well over a millennium older than previously thought.
