At the time of their construction and for many years after, the Pyramids of Giza were the tallest structures on the planet. Khufu's pyramid originally rose 479 feet but has been reduced to 449 feet with the loss of its limestone casing. Khafre's Pyramid had stood 471 feet at its completion while Menkaure's Pyramid stands at a modest 218 feet. In 1300 AD the Great Pyramid was surpassed as the tallest structure in the world by England's Lincoln Cathedral but to this day remains the most massive structure on Earth.

Urban development reaches right up to the perimeter of the antiquities site. The ancient sites in the Memphis area, including those at Giza, together with those at Saqqara, Dahshur, Abu Ruwaysh, and Abusir, were collectively declared a World Heritage Site in 1979.[1]

The Giza pyramids have been recorded in the Giza Plateau Mapping Project run by Ancient Egypt Research Associates, directed by Dr. Mark Lehner. In addition, Lehner's team undertook radiocarbon dating on material recovered from the exterior of the Great Pyramid.[2] Aera's 2009 field season was recorded in a blog.[3]
