● Original height: 146.6 m (481 ft), making it the tallest human-made structure for nearly 4,000 years—an engineering record unmatched until the Middle Ages.
● Base: 230.3 m per side (756 ft), covering about 13 acres—large enough to fit roughly 10 modern football fields.
● Total mass: ~6 million tonnes, constructed from around 2.3 million stone blocks; most weigh 2–3 tons, while some granite blocks reach an astonishing 80 tons.
● Precision alignment: oriented to true north within about 3 arcminutes, likely achieved using stellar observations rather than magnetic tools.
● Extreme leveling: the entire base is level within just 2.1 cm across 5.3 hectares, despite uneven desert bedrock.
