Wikipedia: The Kyrenia ship is the wreck of a 4th century BC 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 salvage expedition 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 National Geographic Society. It is the only preserved ship from Greece's Classical Age. The ship was considered to be very well preserved with approximately 75% of it in good condition. It found a new home at the Ancient Shipwreck Museum in Kyrenia Castle, where it remains on exhibit.
