Which ancient monument is the oldest surviving member of the Seven Wonders of the Ancient World?

The Great Pyramid of Giza is the oldest surviving member of the Seven Wonders of the Ancient World.

Built in Egypt during the reign of Pharaoh Khufu, the pyramid was completed around 2560 BCE. It originally stood about 146.6 metres high and was the tallest human-made structure in the world for more than 3,800 years.

The Great Pyramid formed part of a funerary complex at Giza, alongside pyramids associated with Khafre and Menkaure and the Great Sphinx. Its original outer casing was made from polished limestone, most of which disappeared over later centuries.

The other six ancient wonders have been destroyed or lost, although archaeological remains survive for some of them. The Great Pyramid is therefore the only ancient wonder still substantially standing. It is sometimes called the Pyramid of Cheops, using the Greek form of Khufu’s name.
