The Great Pyramid is the largest of the three pyramids at Giza, an ancient tomb built for pharaoh Khufu around
26002600 to 2600 BC. It is the oldest of the Seven Wonders of the Ancient World and the only one still standing today. Initially, the base is over 230 meters (750 feet) on each side, and its original height was approximately 147 meters (481 feet). The pyramid is famous for its massive size, incredible precision, with a base level within 2.12.1 to 2.1 cm, and the sides are almost perfectly aligned, demonstrating advanced engineering skills. Created from millions of stone blocks, it is constructed from approximately 2.32.3-2.3 million limestone blocks, each weighing an average of 2.52.5 to 2.5 tons, which were transported on sledges and lifted into place using ramps. Skilled laborers, not slaves, worked in a highly organized system to cut, move, and position the stones, a process that involved moving blocks from nearby quarries for the interior and a more distant source for the outer casing. A combination of external and internal ramps was likely used as the pyramid grew, potentially with water used to ease the dragging of sleds by Skilled laborers, not slaves. These laborers worked in a highly organized system to cut, move, and position the stones. This process involved moving blocks from nearby quarries for the interior and a more distant source for the outer casing. A combination of external and internal ramps was likely used as the pyramid grew, potentially with water being poured on the sand in front of the sledges to reduce friction.
Initially, it was built as a tomb for Pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom, The pyramid also contains a complex interior with a descending and ascending passageway, a "Queen's Chamber," a "Grand Gallery," and the main burial chamber, the "King's Chamber," which is lined with granite Above the King's Chamber are five "stress-relieving" chambers made of massive granite blocks to support the immense weight of the masonry above. and is the only one of the original Seven Wonders of the Ancient World that remains largely intact today as a testament to the ancient Egyptians' beliefs in the afterlife and their advanced culture, and many visitors are drawn to the site for its spiritual and mystical significance.
