Which ancient wonder is the only one still largely intact?

The Great Pyramid of Giza is the only surviving wonder of the ancient Greek list of Seven Wonders. Built for the Egyptian pharaoh Khufu, it remains largely intact after roughly 4,500 years, although its original smooth outer casing and pyramidion are missing.

Construction took place during Egypt’s Fourth Dynasty, probably in the 26th century BC. The pyramid originally stood about 146.6 metres tall and was the world’s tallest human-made structure for thousands of years. It was built from enormous quantities of limestone, with granite used in important interior chambers.

The other ancient wonders disappeared through earthquakes, fires, destruction, or gradual loss. The Hanging Gardens of Babylon are especially unusual because historians still debate whether they existed at all, while the Lighthouse of Alexandria and Colossus of Rhodes were destroyed by earthquakes.

“Largely intact” does not mean untouched. Medieval builders removed much of the white Tura limestone casing, and the structure lost its summit. Its core, however, still survives at Giza, making it the sole ancient wonder visible today.
