-workers used round, harder than granite rock to pound away granite -day after day, month after month -until trench formed the side of the obelisk on both sides
-workers would hew the obelisk from the quarry -then transport it by large Ancient Egyptian boats or barges -on the Nile River to the designated location -for over 1000 kilometres away
