Closer to the Great Pyramid
The Great Pyramid is the oldest and largest of the three pyramids in the Giza complex. It rises 480 feet from the desert sands and is comprised of more than 2 million stone blocks of limestone and granite - some weighing 15 tons. Its purpose was as a tomb for Pharaoh Khufu and took 10 to 20 years to build concluding around 2560 BC.
The group of people to the right in the picture are entering a tunnel that leads to an internal labyrinth of rooms and tunnels including a funerary chamber, a Grand Gallery and a recently discovered void which may contain a throne although this has yet to be determined.
