The Great Pyramid of Giza is one of the most iconic structures in the world, built around 2580–2560 BC as a tomb for the Egyptian 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 is composed of approximately 2.3 million blocks of stone, each weighing between 2.5 to 15 tons. The pyramid is part of a complex that includes the Sphinx and several smaller pyramids, showcasing the grandeur of ancient Egyptian civilization and its architectural prowess.
