A large chamber, never-before observed, has been discovered in the Great Pyramid at Giza.

The previously unknown space was announced Thursday by an international team of researchers who used cosmic ray detectors to discern the presence of what they call a “big void” inside the pyramid’s structure as part of the Scan Pyramids project. The void lies just above the Grand Gallery passageway that leads to the King’s chamber within the massive monument, and appears to be over 100 feet long.

If the researchers are correct, this would be the first large chamber to be discovered within the pyramid since the Islamic Caliph al-Ma’mun battered his way into the structure in the ninth century. There are currently just three known chambers within the pyramid: An apparently unfinished room beneath the bedrock, and the King and Queen’s chambers which lie deep within the pyramid itself.
