The last great mystery of the pyramids could be closer to being found thanks to a robot built in Leeds.
Images captured by a new 'micro snake' camera travelling deep within the Great Pyramid of Giza in Egypt reveal small hieroglyphs written in red paint on the floor of a small, hidden chamber.
Egyptologists believe that if deciphered the markings could unlock the secrets of why tunnels, doors and secret chambers were built within pyramids such as this one.
The pyramid is the last of the seven wonders of the ancient world still standing, and is thought to have been built as a tomb for Pharoah Khufu, who ruled in the Fourth Egyptian Dynasty and died in 2566 BC.
Khufu had the Great Pyramid of Giza built as a monumental tomb, inside of which are tomb chambers, ante-rooms, chambers, ventilation shafts and access tunnels.
There are three main chambers: The King's Chamber, the Queen's Chamber and the Grand Gallery.
The King's Chamber has two shafts connected to outside, but two tunnels from the Queen's Chamber deep inside the widest part of the pyramid have two stone doors.
