The Pyramids of Giza, just outside Cairo in Egypt, represent one of the greatest architectural feats by man. The last surviving member of the Seven Wonders of the World, the Great Pyramid of Giza is one of the world’s oldest tourist attractions, built more than 5000 years ago.
There are in fact three main pyramids in Giza; the Great Pyramid of Khufu (or Cheops), The Pyramid of Kafhre and the smaller Pyramid of Menkaura. Each Pyramid is a tomb to a different King of Egypt. In front of the pyramids lies the Sphinx, or Abu al-Hol in Arabic, “Father of Terror”.
Giza’s three pyramids and the Sphinx were thought to have been constructed in the fourth dynasty of Egypt’s Old Kingdom, arguably the first great civilization on earth. For most of us that translates in to about 5000 years ago. Even though there is still debate about how the pyramids at Giza were built, most are in agreement it wasn’t by aliens . It is believed about 20,000 laborers were used and approximately 2 million blocks of stone, each weighing 2.5 tons, just to build the Pyramid of Khufu. For an in depth account of how they were built and a virtual tour inside the Great Pyramid (Khufu).
