The gunman climbed midway up the Pyramid of the Moon around noon and opened fire at throngs of tourists below before finally turning the gun on himself,

A new computational study suggests the Great Pyramid of Giza was built using a sophisticated "Integrated Edge-Ramp" (IER) system, potentially solving a 4,500-year-old architectural enigma. This model challenges traditional theories of massive external ramps or complex internal spirals,

There are more than 100 pyramids in Egypt, but this was the first, built during the reign of Pharoah Djoser (2630 B.C. to 2611 B.C) as a grand mausoleum for himself. Previous pharaohs’ tombs were flat-topped mounds made mostly of mud, but Djoser’s ...

Have they finally solved the ancient Egyptians’ pyramid scheme? Aliens might not have built the pyramids — but the ancient Egyptians might’ve had a pretty cool hack nonetheless. A cutting-edge 3D model suggests that the Great Pyramid of Giza was constructed using a special concealed ramp that might’ve allowed them to build it in less than two decades,

The Neolithic Age may be something of a misnomer, falsely offering stone rather than perishable wood as the period’s primary building material, but its monumental architectures sure make a compelling counterpoint. England has massive stone circles ...
