Professor Ünal Akkemik from the forest engineering department at the forestry faculty of İstanbul University has said that the ships, dating back to the fourth century, were mainly made of oak. Noting that they are confident of uncovering the dates and methods of construction, Akkemik said: "So far 36 ships have been retrieved during the excavations, and I have conducted wood-related assays on 27 of them. We have completed our studies on 20 vessels. These ships were built mainly using oak trees as well as plane, chestnut, pine, cypress, common ash and beech. Some vessels were largely made of oak but had chestnut for the outer portions and oak for inner components. Others were mainly constructed using pine trees."
Excavations during the Marmaray project had uncovered several archeological sites that would open a new chapter in the history of İstanbul, the Byzantine Empire and the world. These sites include secret passages, tombs, churches, works from the Bronze Age, ports, vessels and city walls that have been unknown to us until now. The archeological site at Yenikapı uncovered the ancient Port of Theodosius and with it, 36 sunken ships dating back from the fourth century were exposed to the light of day.
