The Great Pyramid of Giza, the largest of the Giza pyramid complex, is formally known as the Pyramid of Khufu. Constructed during the Fourth Dynasty for the pharaoh Khufu (Cheops in Greek), it was built over approximately 20 years, concluding around 2560 BC. Originally standing at 146.6 metres (481 feet), erosion has reduced its height to approximately 138.8 metres (455 feet). For over 3,800 years, it was the tallest man-made structure in the world, a testament to ancient Egyptian engineering and architectural prowess. The pyramid served not only as a tomb for the pharaoh but also held symbolic and religious significance, reflecting beliefs about the afterlife and the sun god Ra. Today, it remains an iconic symbol of Egypt and one of the Seven Wonders of the Ancient World, attracting millions of visitors annually.
