in your mind, 1000 tons is huge. in reality, it's a 35'x35'x35' piece of granite, so you could fit about 6 inside a hs gym with the ability to walk around.  a hs gym filled with cheap concrete would weigh over 2000 tons and we have seen blocks that were cut on all 6 sides and placed on the ground so yes, we believe they were moved but not sure how.
