The Space Shuttle, fully assembled, weighs somewhere around 3 or 4 million pounds (with no liquid fuel), which comes out to 2 thousand tons. The assembled shuttle is moved via a large crawler vehicle several miles in 2 days from the assembly building to the launch pad. The assembled shuttle stands over 180 feet tall. I seriously doubt that any blocks moved by the ancients outscale the Space Shuttle.
