The Great Pyramid of Giza

The Great Pyramid of Giza

Hello friends today i ll tell you about The oldest monument of the Seven Wonders of the Ancient World, the pyramid is the biggest one in Giza Necropolis.The Great Pyramid of Giza, also known as the Pyramid of Khufu or the Pyramid of Cheops is the only standing ancient wonder of the world. Even after four and a half millenia, the structure still holds some mysteries within.By strategically placing detectors within the pyramid, scientists can track the flow of muons. No muons are absorbed in cavities, but stone can absorb some of them. The scanning takes months or years, for an image to emerge with a high enough contrast between dense and empty areas.

There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called Queen's Chamber and King's Chamber are higher up within the pyramid structure. The main part of the Giza complex is a setting of buildings that included two mortuary temples in honour of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

The Great Pyramid consists of an estimated 2.3 million blocks which most believe to have been transported from nearby quarries. The Tura limestone used for the casing was quarried across the river. The largest granite stones in the pyramid, found in the "King's" chamber, weigh 25 to 80 tonnes and were transported from Aswan, more than 800 km (500 mi) away. Traditionally, ancient Egyptians cut stone blocks by hammering into them some wooden wedges, which were then soaked with water. As the water was absorbed, the wedges expanded, causing the rock to crack. Once they were cut, they were carried by boat either up or down the Nile River to the pyramid. It is estimated that 5.5 million tonnes of limestone, 8,000 tonnes of granite (imported from Aswan), and 500,000 tonnes of mortar were used in the construction of the Great Pyramid.

The Great Pyramid is surrounded by a complex of several buildings including small pyramids. The Pyramid Temple, which stood on the east side of the pyramid and measured 52.2 metres (171 ft) north to south and 40 metres (130 ft) east to west, has almost entirely disappeared apart from the black basalt paving. There are only a few remnants of the causeway which linked the pyramid with the valley and the Valley Temple.
