"In 1993, on an Institute of Nautical Archaeology (INA) shipwreck survey along the western Turkish coast, the Kızılburun column wreck was discovered. At present, excavated ceramics suggest the date of the Kızılburun shipwreck lies in the first century B.C.E.; the Late Hellenistic period (323-31 BCE). Analyses of the marble consignment have revealed that the ship carried a primary cargo of architectural elements quarried on the island of Proconnesus [PDF]. Subsequent investigations point to a likely destination of the ancient city of Claros on the Karian coast of Asia Minor (modern day Turkey)."

The ship is believed to have been carrying marble for the construction of a temple at Claros. According to Archaeology (2009), the ship was transporting the pieces of a marble column in eight giant drums. The pieces, when stacked up on top of each other, "would have formed a 30-foot-high Doric column." According to one of the archaeologists working at the site, "[u]sing a ship like this one would have required 20 voyages to supply enough marble for the 14 known columns at Claros."
