"The Stone of the South" at Baalbek Lebanon, didn't quite make it to the ‘Temple of Jupiter’ and we don't know why exactly. It was abandoned there thousands of years ago, weighing in at approximately 1242 tons. Interestingly enough, the blocks originated in a nearby limestone quarry half a mile away and how they were able to move it around is a mystery. But there's a particular notion that they had anti gravity technology which was more than likely given to them by other beings from another world in the milky way galaxy.
