Wooden barges transported stone blocks via canal from the river or quarry to the pyramid. The canal at the base of the pyramid was at a higher elevation than the canal used to transport building materials from the river or quarry.
Many people have said that the pyramids would last 1 million years or even until the world ended, but I'd say around 10,000 to 100,000 years based on current observations.
But what the Egyptians lacked in tools, they made up for with science and engineering precision. Smith explains that they developed and used the cubit rod to measure and lay out the dimensions of the pyramid; a square level to level horizontal surfaces, and a 3:4:5 framing square to create precision 90-degree angles.
While the pyramid was originally built by 4,000 workers over the course of 20 years using strength, sleds and ropes, building the pyramid today using stone-carrying vehicles, cranes and helicopters would probably take 1,500 to 2,000 workers around five years, and it would cost on the order of $5 billion, Houdin said, ...
The unknowns of pyramid construction chiefly center on the question of how the blocks were moved up the superstructure. There is no known accurate historical or archaeological evidence that definitively resolves the question.
The pharaoh's final resting place was usually within a burial chamber underneath the pyramid. Although the Great Pyramid has subterranean chambers, they were never completed, and Khufu's sarcophagus rests in the King's Chamber, where Napoleon is said to have sojourned, deep inside the Great Pyramid.
Professor Michel Barsoum and colleagues have found scientific evidence that parts of the Great Pyramids of Giza were built using an early form of concrete, debunking an age old myth that they were built using only cut limestone blocks.
A hidden corridor nine meters (30 feet) long has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza, and this could lead to further findings, Egyptian antiquities officials said on Thursday.
The pyramids at Giza might have been aligned to two northerly stars. By looking at the stars, an Egyptologist claims to have found a new way to date the pyramids of Giza and other ancient sites.
The pyramids line up -- more or less -- along this line. The ancient Egyptians aligned their pyramids and temples to the north because they believed their pharaohs became stars in the northern sky after they died. But while the Great Pyramid is aligned with the north, the other pyramids are all slightly off.
How does the pyramid fit into early Egyptian life? Pyramids today stand as a reminder of the ancient Egyptian glorification of life after death, and in fact, the pyramids were built as monuments to house the tombs of the pharaohs. Death was seen as merely the beginning of a journey to the other world.
In the 12th century, Kurdish ruler al-Malek al-Aziz Othman ben Yusuf attempted to destroy one of the pyramids, but only successfully damaged the smallest, leaving a vertical gash on the north face.
