It was the second port of Ancient Corinth, where pioneering methods of port construction were also applied. There were two sections: the commercial and the military. It was named after Kekchrios, the twin brother of Lehi, son of Piraeus and Poseidon. This harbor was partly natural, as it had northern and southern capes, and partly artificial, as two breakwaters – horseshoe-shaped piers, about 30 meters high from the sea floor – were constructed extending from the capes, creating a large harbor basin and leaving an entrance 120 meters wide
The greatest width of the harbor was 280 meters, and the greatest distance from the central pier to the breakwaters at the entrance was 210-215 meters. On the northeast side, a pier 17 meters wide and 106 meters long was constructed, and another pier of approximately the same width and 170 meters long was built opposite. Extensive archaeological excavations have been carried out in the harbor, revealing a wealth of information and many finds, with the rarest being a series of paintings made of glass fittings (a precursor to today’s stained glass), which are kept in the Museum of Isthmia. In the harbor, in addition to the very extensive warehouses, shops, and public buildings, which were most developed during the Roman period, a temple dedicated to Aphrodite, Isis, and early Christian temples have been discovered. It was from this port that St. Paul traveled to Rome during his great tours for the spread of Christianity.
