19,500-lb oversized block discovered at Great Pyramid course 206. James Dawkins in 1751 measured a stone at course 206 that was 6 ft 6 in square, weighing approximately 20,500 lb (9,300 kg) Michael Eniman in 1711 measured the same stone at 6.5 ft x 6 ft x 3 ft, weighing approximately 18,500 lb Giovanni Batista Bora sketched and measured the top three courses in 1751, documenting the oversized stone

A massive block at course 206 weighed ~19,500 lb and had to be raised 456 ft above the base — far harder than moving the 80-ton granite beams below. This single stone contradicts ramp-based construction theories. 📐🧱

Key Facts

  • James Dawkins in 1751 measured a stone at course 206 that was 6 ft 6 in square, weighing approximately 20,500 lb (9,300 kg)
  • Michael Eniman in 1711 measured the same stone at 6.5 ft x 6 ft x 3 ft, weighing approximately 18,500 lb
  • Giovanni Batista Bora sketched and measured the top three courses in 1751, documenting the oversized stone
  • Bora's measurements of 6'4 in by approximately 6'3 in conform to other explorer recordings
  • The estimated weight of 19,500 lb (8,800 kg) is calculated as the midpoint of the range
  • This single block contradicts pyramid construction theories including Mark Lehner's ramp models
  • The block was a core block, never meant to be seen, and could have been five separate 2-ton blocks
  • Course 206 was at least the 20th thickest course on the entire pyramid
  • The block had to be raised 456 ft above the base, presenting a greater challenge than moving the 80-ton granite beams low on the pyramid
