The Kyrenia Ship is the wreck of a 4th-century BC ancient Greek merchant ship. It was discovered by Greek-Cypriot diving instructor Andreas Cariolou in November 1965 during a storm. Having lost the exact position, Cariolou carried out more than 200 dives until he re-discovered the wreck in 1967 close to Kyrenia in Cyprus. Michael Katzev, a graduate student at the University of Pennsylvania Museum of Archaeology and Anthropology, directed a scientific excavation from 1967–69. Preservation of the ship's timbers continued during the winter of 1970. Katzev later was a co-founder of the Institute of Nautical Archaeology. The find was extensively covered in a documentary by the Cyprus Broadcasting Corporation titled "With Captain, Sailors Three: The Ancient Ship of Kyrenia"]. The ship itself was very well preserved with approximately 75% of its hull in good condition. It found a new home at the Ancient Shipwreck Museum in Kyrenia Castle, where it remains on exhibit.
