Coinciding with the hotly anticipated British Museum exhibition Sunken Cities: Egypt`s Lost Worlds in May 2016, this is the sensational story of two magnificent ancient aquatic cities which once stood at the mouth of the river Nile. Gateways to the land of the pharaohs, Thonis-Heracleion and Canopus were thriving, busy ports - until a catastrophe caused them to sink beneath the water. Now the ruins, and the objects and artefacts found among them, reveal how their inhabitants lived, worshipped and interacted with their foreign visitors.
