View looking east from the shore at the remnants of the southern mole of the port of Cenchreae. Due to seismic activity the harbor of Cenchreae has sunk about 7.5 ft [2.3 m.] from the New Testament era. These buildings were part of the warehouses of the port area. More specifically, in Paul's day this basilica shaped structure may have been a temple for the deity Isis. Later it may have been turned into a church dedicated to Phoebe.
