apr 8, 2550 BC - 17 Great Pyramids of Giza
Khufu, Khafre, Menkaure
The pyramid contains an estimated 2,300,000 blocks, some of which are upwards of 50 tons. Like the pyramids built by his predecessor Snefru and those that followed on the Giza plateau, Khufu’s pyramid is constructed of inner, rough-hewn, locally quarried core stones, which is all we see today, and angled, outer casing blocks laid in even horizontal courses with spaces filled with gypsum plaster.
