The Pyramids of Giza are monumental tombs constructed during Egypt's Old Kingdom, specifically in the Fourth Dynasty around the mid-third millennium BCE. Built by three pharaohs - Khufu, Khafre, and Menkaure - these massive structures were designed as eternal resting places that would help the rulers transition to the afterlife. The Great Pyramid of Khufu, the largest of the three, originally stood hundreds of feet tall and was constructed using millions of stone blocks, with each block weighing several tons. Located on the Nile's west bank near Cairo, these pyramids were not just burial sites but powerful symbols of royal authority, showcasing the extraordinary engineering and architectural skills of ancient Egyptians. They remain the only surviving wonder of the ancient world and continue to fascinate scholars and visitors alike with their precise construction and historical significance.
