The ancient wonder located in Egypt is the Great Pyramid of Giza. This iconic structure is one of the most remarkable achievements of ancient engineering and was built as a tomb for Pharaoh Khufu around 2580–2560 BC. The Great Pyramid stands as the largest of the three pyramids at Giza and was originally 146.6 meters tall, though today, it stands at approximately 138.8 meters due to the loss of the outer casing stones. It showcases sophisticated knowledge of mathematics and architecture, and it is the only surviving structure of the original Seven Wonders of the Ancient World, drawing millions of visitors each year.
