As early as around 2000 BC, a magnificent Assyrian temple tower, or "templo mayor Tower", was built in city of ur, one of the oldest Sumerian cities in the lower reaches of the ancient Euphrates River (now Iraq), and was later called the birthplace of the roof garden.

In the early 1920s, when excavating this architectural site, the famous British archaeologist Lund? Sir Leonard Woolley found traces of planting trees on the third floor of the tower. These pyramid-shaped man-made mountains are typical features of ancient Mesopotamian cities in the two river basins. The ancient Assyrian temple tower is mainly a large-scale religious building, followed by a beautified "garden", including terraces, steps and some temples with layered plants at the top. However, the heritage of these ancient civilizations was completely destroyed by Mongolian cavalry.

The garden-like Assyrian ancient temple tower is not a real roof garden, because the only plants on the tower are not planted on the "roof". The real roof garden that people say is the "hanging garden" that appeared in New Babylon more than 500 years after the ancient temple tower of Assyria 1.
