Answer:
The answer is: the Babylonians (or to be precise, the Chaldea people)
Step-by-step explanation:
However, we have to keep in mind that Babilonia was governed by two kinds of people on its History - the Amorites and subsequently, the Chaldea people. Between the years of 625 BC and 605 BC, Babilonia expanded its domains over other territories, and under the reign of Nebuchadnezzar II, became an empire. It was under the rule of Nebuchadnezzar that several architectonical achievements were done, such as the Ishtar Gate, some sources say that a tower in honor of the god Marduk was also built, and especially, the Hanging Gardens, and several other buildings.
