The Great Pyramid contains 4 mysterious small shaft ‘channels’ within its superstructure. These channels connect the King’s Chamber to the pyramid exterior, yet never fully connected the Queen’s Chamber to the outside.

No other Egyptian pyramid has such channels, and they have confounded explorers for thousands of years.

This video looks at the full history of the channels, scrutinizes the most popular theories for their purpose, and reveals new evidence to finally bring resolution.

But like every great discovery, the answer to this mystery brings with it even more interesting questions.
