In Baalbek, Lebanon, researchers are faced with a mystery. Three stones are built into the foundation of a temple that should not actually exist. On top of that, the pillars of the temple are made of a stone that only occurs in Aswan in Egypt, almost 1,500 kilometers away. The transport of heavy stones already poses problems in the present. Stones weighing as much as the largest of Baalbek would have to be lifted by 18 heavy-duty cranes today. Even the components of nearly 100 columns would require incredible convoys of specially secured heavy-duty trucks. But these stones were moved over this distance at a time when there was neither asphalt nor engines.

All this gave rise to speculation: Are the stones of Baalbek also legacies of a much older culture that had advanced technologies? Who could really be behind the construction of the Temple of Baalbek, we look at today in this video.
