The Great Pyramid of Giza is one of the most iconic structures in the world, built around 2580–2560 BC during the reign of Pharaoh Khufu. It is the largest of the three pyramids on the Giza plateau and was originally 146.6 meters tall, making it the tallest man-made structure for over 3,800 years. This remarkable feat of engineering showcases the advanced skills of ancient Egyptian builders. Constructed from approximately 2.3 million blocks of stone, the pyramid served as a tomb for Khufu and reflects the Egyptians' beliefs in the afterlife. It is part of a complex that includes the Sphinx and several smaller pyramids, attracting millions of visitors each year.
