The Bent Pyramid's upper chamber shows surprisingly little damage—just flaking of individual stones. Compare this to the Great Pyramid's King's Chamber which has a single fracture crossing every ceiling beam, or the Red Pyramid with almost every lentil split. New research suggests weathering variability comes down to limestone quality differences, not structural failure. Some damage traces back to ancient quarrying work, evidenced by chisel marks on the stones.
Upper chamber lacks substantial cracks despite erosion

Key facts
- The upper chamber of the Bent Pyramid contains no large fractures, only flaking of individual corbels
- The Great Pyramid's King's Chamber has a single fracture crossing every beam in the ceiling
- The Red Pyramid has almost every lentil split in two
- Weathering variability is due to limestone quality differences, not structural failure
- Some damage to the upper chamber is from quarrying work, evidenced by chisel marks
- Engineer Peter James noted corbel overhangs in the Bent Pyramid and Mum Pyramid were aggressive, but Red Pyramid corbels are only 2-3 cm shorter on average
