23 September 2009 - 4 January 2010. Due to its strategic location as a port between two continents, the city of Byzantium, later christened Constantinople and then Istanbul, has long been a cultural crossroads. Its importance lies in the fact that it is a gateway between two worlds, both by land and sea. As such, the city has has seen its fair share of history. This exhibition examines some of that history, much of which has recently come to light during undersea excavation aimed at linking both sides of the Bosphorus. A selection of some three hundred items from Turkish, French and international collections is included in this show which documents chronologically the history of this great city.
