In this episode, Bettany heads to Turkey. The site of Yenikapi, in Istanbul, is home to one of the largest archaeological digs in the world, covering over 58,000 square metres, discovered during development work. Most of the remains relate to the artificial Theodosian Harbour from the Byzantine period including over 37 remarkably well-preserved shipwrecks, the largest group of Byzantine shipwrecks ever found. The site is a treasure trove of finds, from preserved camel skeletons to a container of cherries. Bettany heads to the conservation lab to see some of these remarkable finds first-hand, and Lucy speaks to one of the archaeologists working on the shipwreck remains.
