ScanLAB Projects has created one of the most epic projects to date. In partnership with BBC One and PBS, they have documented three ancient cities built on the shoulders of civilizations that have evolved over the course of thousands of years.  

Exploring the secret labyrinth of chambers and passages beneath the Giza Pyramids, uncovering the crystal clear waters of subterranean aqueducts that feed the irrigation system of old Athens, discovering how Istanbul has defended itself against marauding invasions and collapse of its magnificent Hagia Sophia dome, all of it can be seen from 29th of August.
