1. The Great Pyramid of Giza While there are several pyramids on the Giza Plateau near Cairo, Egypt, the largest is the Great Pyramid of Giza. This pyramid, built circa 2600 BCE, is 146 metres tall with a base of 230 metres. It is made of two million blocks of stone with an average weight of 2.3 metric tonnes. One of the greatest engineering mysteries is how such heavy blocks were built into a pyramid shape thousands of years ago. Cranes as we know them today were certainly not around.
