On Tuesday evening, Science Channel's "Unearthed" heads to the Great Pyramid of Giza to examine a "primitive machine" designed to protect the King's Chamber. Housing the remains of Pharaoh Khufu (2551–2528 B.C., approximately), who ordered the construction of the Great Pyramid of Giza, Live Science provides a brief explanation of how the elaborate system outside the King's Chamber worked.

To protect the pharaoh's chamber, ancient Egyptians constructed a series of grooves and blocks that are hidden beneath the walls of the pyramid. While scholars have known about this system since at least the 19th century, the TV show uses computer animations to present a reconstruction. The animations show how blocks were dropped down grooves near the King's Chamber after the pharaoh' burial. The system was sophisticated for its time, said Lehner, noting that it blocked off the entranceway to the King's Chamber with giant blocks, making it harder for a thief to break in.
