The Great Pyramid of Giza, often referred to as a wonder of the ancient world in Egypt, is the most famous of the pyramids. Constructed around 2580–2560 BC, it served as a burial site for Pharaoh Khufu. This architectural marvel, originally standing at about 146.6 meters (481 feet), was the tallest man-made structure for over 3,800 years. Examples of ancient Egyptian engineering, the Great Pyramid is comprised of approximately 2.3 million blocks of limestone and granite. It continues to fascinate historians, archaeologists, and tourists alike, symbolizing Egypt's rich cultural heritage.
