The ancient structure known for being a wonder of the world is the Great Pyramid of Giza. Located in Egypt, it is the oldest of the Seven Wonders of the Ancient World and the only one that remains largely intact. Built as a tomb for the Pharaoh Khufu around 2580–2560 BC, it was originally 146.6 meters tall and was constructed using approximately 2.3 million stone blocks. The pyramid is a testament to ancient engineering and remains a significant historical and tourist attraction today.
