Which ancient wonder was traditionally said to have been in Babylon?

The Hanging Gardens of Babylon were traditionally said to have been located in Babylon.

Ancient writers described the gardens as a spectacular elevated landscape of trees and plants, supposedly built in the Babylonian capital. One tradition attributes them to King Nebuchadnezzar II, who ruled from 605 to 562 BC, and says they were created for his Median wife, Amytis, although that story is not independently confirmed by Babylonian records.

The gardens create an important historical puzzle. No surviving Babylonian inscription clearly records them, and archaeologists have not found decisive remains at Babylon. Some modern scholars therefore suggest that later Greek writers confused Babylon with Nineveh, where the Assyrian king Sennacherib described elaborate gardens and water-lifting systems.

Unlike the Great Pyramid, the gardens cannot be securely matched to a surviving monument. Their inclusion in the traditional list reflects their fame in classical literature, while their exact location and even historical existence remain debated.
