Is the oldest and largest of the pyramids of the Giza pyramid complex. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact.
Egyptologists conclude that the pyramid was built as a tomb for the Fourth Dynasty Egyptian pharaoh Khufu and estimate that it was built in the 26th century BC during a period of around 27 years.
Initially standing at 147 meters, the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Throughout history the majority of the smooth white limestone casing was removed, which lowered the pyramid’s height to the present 139 meters. What is seen today is the underlying core structure. The base was measured to be about 230 meters square.
There are three known chambers inside the Great Pyramid. The lowest was cut into the bedrock, upon which the pyramid was built, but remained unfinished. The so-called Queen’s Chamber and King’s Chamber, that contains a granite sarcophagus, are higher up, within the pyramid structure. Khufu’s vizier, Hemiunu, is believed by some to be the architect of the Great Pyramid.
