Grant Frame, Ph.D., Associate Curator, Babylonian Section. The Babylonian king Nebuchadnezzar II (604–562 BCE) is infamous in the Bible for having destroyed the Temple of Jerusalem in 586. However, he is famous in classical sources for having built the Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World. During his reign, Nebuchadnezzar commissioned numerous building projects at Babylon and the remains of many of these were found by the German archaeologist Robert Koldewey, who conducted extensive excavations at Babylon from 1899 until the outbreak of the First World War. But did he find the remains of the Hanging Gardens? That is the million-dollar question.
