This block of stone measures 64 feet by 19.6 feet by 18 feet. Weighing in at 1,960 tons, it's the largest known surviving block of stone carved by humans.
The German Archaeological Institute discovered it at Baalbeck, a site in Lebanon. It dates back to at least 27 B.C., and was probably made long before that. Archaeologists think that the block was probably carved for local temple construction, most likely for a nearby temple for the Roman god Jupiter. But the block cracked en route and was abandoned at the quarry.
