ATHENS, GREECE—A submerged port has been mapped at the site of Lechaion, the western harbor of ancient Corinth, according to an announcement made by the Greek Ministry of Culture and published in The Greek Reporter. A team made up of members of the Underwater Antiquities Ephorate of the ministry, the SAXO Institute of the University of Copenhagen, the Danish Institute in Athens, and the University of Patras used a 3-D parametric sub-bottom profiler to examine an entrance channel, a pier, and eight caissons filled with pebbles mixed with mortar. The caissons, found nowhere else in Greece, may have been intended for the construction of another pier. To read about the excavation of a similar site, see "Diving Into History: Liman Tepe Harbor."
