Proposed integrated system using portcullis and Grand Gallery to seal the chamber. The speaker extends Christiansen's idea by linking the plug block to the portcullis mechanism via four ropes feeding into grooves at the southern end of the antechamber Opening the chamber would simultaneously lift the portcullis blocks and pull a counterweight up the Grand Gallery, which could be wedged in place using existing slots and grooves To close the chamber, counterweights in the Grand Gallery would be gently lowered while people manned ropes from both channel exits to control motion
Building on Christiansen's work, a proposed integrated system links the plug block to the portcullis via four ropes feeding into antechamber grooves. Opening the chamber lifts the portcullis and draws a counterweight up the Grand Gallery, wedged into existing slots. The Manicular Tunnel may have been an ancient rope repair.
Key Facts
- The speaker extends Christiansen's idea by linking the plug block to the portcullis mechanism via four ropes feeding into grooves at the southern end of the antechamber
- Opening the chamber would simultaneously lift the portcullis blocks and pull a counterweight up the Grand Gallery, which could be wedged in place using existing slots and grooves
- To close the chamber, counterweights in the Grand Gallery would be gently lowered while people manned ropes from both channel exits to control motion
- Grand Gallery anomalies—slots, sockets, scratch marks, and a high ceiling groove—hint at now-missing infrastructure for such a mechanism
- The chamber could only be opened from outside, making robbery difficult and explaining why the portcullis was eventually destroyed
- The Manicular Tunnel near the end of the northern channel may have been created in antiquity to fix a problem with the ropes
