Getting lost in history

 I watched this wonderful documentary on a lost harbor. I can get completely lost on YouTube in free documentaries.

In the heart of a metropolitan city of 15 million people and among the construction of a new billion-dollar transportation network, an archaeological sensation has been discovered: the ancient harbour of Theodosious. Theodosious was the last ruler over both Eastern and Western portions of a unified Roman Empire; the harbour has been buried and shrouded in mystery for over 800 years … until now. Istanbul, Turkey, is situated exactly between Europe and Asia. It has, since prehistoric times, bridged the gap between these continents, their cultures and its people. Engineers are working to connect East to West through a spectacular 1.4 kilometer railway tunnel, 60 meters below the surface, but they've been stalled by the discovery of the Emperor's Lost Harbor.  

Theodosius I (Ancient Greek: Θεοδόσιος Theodosios; 11 January 347 – 17 January 395), also known as Theodosius the Great, was Roman emperor from 379 to 395. He won two civil wars and was instrumental in establishing the Nicene Creed as the orthodox doctrine for Nicene Christianity. Theodosius was the last emperor to rule the entire Roman Empire before its administration was permanently split between the Western Roman Empire and the Eastern Roman Empire. He ended the Gothic War (376–382), but did so on terms disadvantageous to the empire, with the Goths remaining and politically autonomous within Roman territory, albeit as nominal allies.
