The Giza Pyramids, built to endure an eternity, have done just that. The monumental tombs are relics of Egypt's Old Kingdom era and were constructed some 4,500 years ago. Egypt's pharaohs expected to become gods in the afterlife.
In addition to Khufuâs pyramid, two other large pyramids for pharaohs were erected at the Giza site, one for his son Khafra (it originally stood 471 feet high) and the other for Khafraâs son Menkaure (originally 218 feet high). Khafraâs pyramid complex is home to the famous Great Sphinx statue, which measures 241 feet long and about 66 feet high. Over the ages, all three pyramids have been targeted by grave robbers and much of their exterior white limestone stolen, possibly for use in other building projects.
