Egypt is known for the Great Pyramids and the Sphinx. The Great Pyramids, particularly the Pyramid of Khufu at Giza, are some of the most remarkable architectural achievements in human history. Built as monumental tombs for pharaohs during the Fourth Dynasty of the Old Kingdom, these pyramids reflect ancient Egypt's advanced engineering skills and religious beliefs. The Sphinx, a colossal limestone statue with the body of a lion and the head of a human, is believed to represent the pharaoh Khafre. Together, these iconic structures draw millions of tourists and serve as symbols of ancient Egyptian civilization and culture.
