Archeologists believe they may have discovered how the Great Pyramid of Giza was built 4500 years ago in Egypt.
According to LiveScience, archeologists may have unearthed the system responsible for pulling such stones up a slope at an ancient alabaster quarry at Hatnub. And it may have been used to build the Great Pyramid – made of 2.3 million blocks averaging 2.5 tonnes each.
“This system is composed of a central ramp flanked by two staircases with numerous post holes,” Yannis Gourdon, co-director of the mission said. “Using a sled which carried a stone block and was attached with ropes to these wooden posts ... they were able to pull up the alabaster blocks out of the quarry on very steep slopes of 20 per cent or more.”
