Why does the Great Pyramid have a hidden corridor behind its entrance vault?

The Entrance Vault to the Great Pyramid and ScanPyramids corridor explained · 26:34 · Video: History for GRANITE · Watch at the source

In short: For centuries, the massive chevron blocks above the Great Pyramid entrance have puzzled researchers. A 2016 discovery revealed a mysterious hidden space behind them. This video reconstructs the original vault design to investigate what Old Kingdom engineers were actually building and why.

The gabled chevron blocks, crafted from Tura limestone, form a saddle vault ceiling that has long defied explanation. Because the corridor beneath these blocks does not appear to require weight relief, their structural purpose remains unclear. In 2016, the ScanPyramids mission identified a hidden, corridor-like void situated directly behind these blocks, a finding that remains largely uninvestigated by mainstream Egyptology.

By meticulously reconstructing the partially ruined entrance vault, this analysis attempts to determine the original architectural intent. By linking the newly discovered ScanPyramids corridor with the existing vault structure, the video seeks to uncover the functional logic behind these ancient construction techniques and the broader objectives of the Old Kingdom builders.
