The Great Pyramid of Khufu at Giza

is the largest single building ever constructed. Originally 479 ft (146 m) in height, it still stands at an awe-inspiring 449 ft (137 m). Most of its height loss is due to the stripping of its original smooth limestone casing.

When the Greek historian Herodotus visited Giza in about 450 BC, he was told by Egyptian priests that the Great Pyramid had been built for the pharaoh Khufu (Cheops to the Greeks), who was the second king of the Fourth Dynasty (c.2575–c. 2465 BC).

The priests told Herodotus that the Great Pyramid had taken 400,000 men 20 years to build, working in three-month shifts of 100,000 men at a time. This is not implausible, but archaeologists now tend to believe a more limited workforce may have occupied the site without the need for shifts. Perhaps as few as 20,000 workers, with an accompanying support staff (bakers, physicians, priests, etc.), would have been adequate to the task.

The Great Pyramid was made of 2.3 million stone blocks, weighing from 2 to 15 tons each. When completed, the Great Pyramid of Khufu weighed 6 million tons, the weight of all Europe's cathedrals put together! The pyramid was also the tallest structure in the world for thousands of years, until it was surpassed by the spires of England's Lincoln Cathedral around 1300 AD.

The second-largest pyramid of Giza was built for Khufu's son Khafre (Chephren), who became the fourth king of the Fourth Dynasty after the death of his short-lived elder brother and died c.2532 BC. Although many of his relatives were hastily buried in cheap tombs, the Pyramid of Khafre is almost as vast as the Great Pyramid of his father.

Khafre's pyramid actually looks taller than the Great Pyramid of Khufu because it stands on a slightly higher part of the plateau, it has a steeper angle, and it is the only one with a smooth limestone cap. Khafre's pyramid measures 707 ft (216 m) on each side and was originally 471 ft (143 m) high; its limestone and granite blocks weigh about 2.5 tons each.

Like the Great Pyramid, Khafre's Pyramid included five boat pits (with no boats), together with mortuary and valley temples and a connecting causeway some 430 yards long carved out of the living rock. The burial chamber, which is underground, contains a red granite sarcophagus with its lid. Next to this is a square cavity that presumably once held the chest containing the pharaoh's insides. The Great Sphinx, near Khafre's pyramid, is believed to be a royal portrait of Khafre.

The southernmost and last of the pyramids to be built was the Pyramid of Menkaure (Mycerinus), son of Khafre and the fifth king of the Fourth Dynasty. Each side measures 356 ft (109 m), and the structure's completed height was 218 ft (66 m).

In addition to these three monuments, small pyramids were built for three of Khufu's wives and a series of flat-topped pyramids for the remains of his favorite children. At the end of a long causeway lined with minor tombs of court officials, a mortuary temple was built just to mummify the pharoah's body.

Like all pharonic tombs, the burial chambers of the pyramids were packed with all the necessities for the next life: furniture, statues of servants (to be enlivened by an incantation when needed), and boats.

The question of how the pyramids were built has not yet found a definitive answer. Herodotus reported that the base was laid, then the great blocks (each weighing about seven tons) were levered into place, a step at a time up all 203 steps. But this cannot be done, as demonstrated by a Japanese attempt at a duplicate in the 1980s. The most plausible explanation is that the Egyptians employed a sloping and encircling embankment of brick, earth, and sand, which was increased in height and in length as the pyramid rose; stone blocks were hauled up the ramp by means of sledges, rollers, and levers.

The pyramids have impressively withstood the ravages of time, but not of grave robbers. They emptied the pyramids of their valuables in ancient times. In 1818 an Italian entered the burial chamber of Khafre with a hydraulic ram, but the gold and other treasures were long gone.
