The Great Pyramid of Giza is one of the most impressive architectural marvels of the ancient world. Located on the outskirts of Cairo, Egypt, the Great Pyramid is the oldest and largest of the three pyramids in the Giza Necropolis. It is believed to have been constructed over a period of 20 years, from around 2580 to 2560 BCE, during the reign of the pharaoh Khufu. This incredible monument stands as a testament to the advanced engineering and architectural skills of the ancient Egyptians.
The Great Pyramid of Giza is a massive structure, standing at a height of 147 meters and covering an area of over 5 hectares. It was constructed using an estimated 2.3 million stone blocks, each weighing an average of 2.5 tons. The precision with which these blocks were cut and placed is astounding, with the joints between them so precise that a sheet of paper cannot fit between them. The fact that the structure has survived for over 4,500 years, despite numerous earthquakes and other natural disasters, is a testament to the quality of the construction.
