Pavlopetri is a salt water dive site, located in Laconia, Greece.
In 1967, Nicholas Flemming discovered something strange in Greece. It looked like not just a single structure, but actually several buildings. A team of archaeologists from Cambridge University came and helped him map his discovery. It turned out to be an entire city. It had buildings, roads, and even tombs. It was named the Pavlopetri, or Paul’s and Peter’s, which is the modern name of the nearby island and beach where the discovery was made. The name of the ancient city, however, remains unknown. At least 15 buildings have been found, including one as recent as 2009. It has been dated back to 2800 B.C., with some of its materials coming from the Bronze Age.
