Ancient Megalithic Stones

AncientX.com - Ancient Astronauts, Planet X, Nibiru, NASA, Face on Mars, Jason Martell Research: "Beneath the temples lay a greater wonder, a huge foundation comprising an area of more than five million square feet and containing more stone than the Great Pyramid at Giza. No mortar was used in its construction and yet in 2000 years it has not perceptibly settled. The secret of this stability lies in the downhill retaining wall, which contains three of the world's biggest blocks of cut stone. Stood upright, each would be as tall as a five story building, and weigh more than 600 tons."
