The history of the pyramids
The great pyramid is believed to have been built over a 20 year period. The site was first prepared, and blocks of stone were transported and placed. An outer casing (which disappeared over the years) was then used to smooth the surface. Although it is not known how the blocks were put in place. One theory involves the construction of a straight or spiral ramp that was raised as the construction proceeded. Thhis ramp, coated with mud and water, eased the displacement of the blocks which were pushed (or pulled) into place. A second theory suggests that the blocks were placed using long levers with a short angled foot.
Throughout their history, the pyramids of Giza have stimulated human imagination. They were referred to as “The Granaries of Joseph” and “The Mountains of Pharaoh”.
Today, the Great Pyramid is enclosed, together with the other pyramids and the Sphinx, in the touristic region off the Giza Plateau. The boat is believed to have been used to carry the body of Khufu in his last journey on earth before being buried inside the pyramid. It may also serve him as a means of transportation in
When it was built, the Great pyramid was 145.75 m (481 ft) high. Over the years, it lost 10 m (30 ft) off its top. It ranked as the tallest structure on Earth for more than 43 centuries, only to be surpassed in height in the nineteenth century AD. Each side is carefully oriented with one of the cardinal points of the compass, that is, north, south, east, and west. The horizontal cross section of the pyramid is square at any level, with each side measuring 229 m (751 ft) in length. The maximum error between side lengths is astonishingly less than 0.1%.
The structure consists of approximately 2 million blocks of stone, each weighing more than two tons. It haas been suggested that there are enough blocks in the three pyramids to build a 3 m (10 ft) high, 0.3 m (1 ft) thick wall around France. On the north face, is the pyramid’s entrance. A number of corridors, galleries, and escape shafts either lead to the King’s burial chamber, or were intended to serve other functions. The King’s chamber is located at the heart of the pyramid, only accessible through the Great Gallery and an ascending corridor. The King’s sarcophagus is made of
New theories concerning the origin and purpose of the Pyramids of Giza have been proposed. Astronomic observatories. Places of cult worship. Geometric structures constructed by a long-gone civilization. Even extraterrestrial-related theories have been proposed with little evidence in support. Great Pyramids were built by the great Ancient Egyptian civilization off the West bank of the Nile as tombs for their magnificent Kings.
