Three Structural Features Reveal Osireion Engineering. Enclosure walls are 6 meters (20 feet) thick sandstone Two thrust beams (1.10m thick, 1.25m wide) discovered connecting central island to east wall at 4.15m depth Bore holes found hard Issawia limestone foundation at approximately 15m depth below central island

The engineering at Osireion is remarkable: thrust beams connecting the central island to the east wall at depth, and granite pillars on the central island. Bore holes hit limestone foundation at depth — extending beyond the wall footprint in places. This was built for serious load-bearing.

Key Facts

  • Enclosure walls are 6 meters (20 feet) thick sandstone
  • Two thrust beams (1.10m thick, 1.25m wide) discovered connecting central island to east wall at 4.15m depth
  • Bore holes found hard Issawia limestone foundation at approximately 15m depth below central island
  • Limestone foundation extends outward beyond enclosure wall footprint (found at 22m depth southeast)
  • 50-ton granite pillars on central island
  • Structural features indicate purpose for load-bearing and stability
