Using advanced imaging technology, a team of archaeologists in Egypt have discovered an enormous empty space inside the Great Pyramid of Giza.
The astounding void measures nearly one hundred feet long and is being heralded as the most significant find from the legendary site in over a century.
Researchers managed to spot the chamber inside the structure by observing tiny particles called 'muons' as they washed over the structure and revealed the heretofore unseen room.
Within the confines of the pyramid, the chamber sits above an area known as the 'Grand Gallery' and appears to have been kept secret since the structure was constructed millennia ago.
