Baalbek Lebanon
Even more puzzling is the largest cut-stone known to exist anywhere which is found in the quarry within sight of the Acropolis, about half a mile away. This quarry was presumably the origin of the massive stones in place in the Acropolis. This stone is 68ft. long and roughly 14 ft. square. Its enormity can be judged by noticing the small figure of a man sitting on its top with his friend just below and slightly to the right.
The challenge is clear. Who and what can move any of these stones today and more importantly how were they moved in the first place?
Cool pictures.
