Roughly 5,000 years of continuous occupation is mapped here. Occupied from around 3000 BC, through the Minoan and Mycenaean periods, and submerged around 1000 BC by earthquake and subsidence. Discovered in 1904, mapped in 1968 by Nicholas Flemming, and digitally surveyed by Nottingham University in 2009 in a project that produced the first full 3D reconstruction of a sunken city.
