Final answer:
The White Temple of Uruk is the oldest (3517-3358 BCE), followed by the Great Temple of Amon-Re at Karnak (1550-1077 BCE), and the Ishtar Gate at Babylon is the most recent (575 BCE).
Step-by-step explanation:
To put the buildings in order from the oldest to the most recent, we must look at the dates when each was constructed. The White Temple of Uruk is the oldest, with its construction period estimated to be around 3517-3358 BCE. It stands atop the Anu Ziggurat and was dedicated to the sky god Anu, signaling its central religious and political significance in the Uruk city-state. Next, the Great Temple of Amon-Re at Karnak in Egypt dates back to various phases, with its significant construction taking place during the New Kingdom, around 1550-1077 BCE, offering a grand and complex religious site dedicated to a key Egyptian deity. Lastly, the Ishtar Gate at Babylon was constructed much later, during the reign of Nebuchadnezzar II, around 575 BCE, serving as a grand entrance to the city of Babylon, decorated with images of dragons and aurochs that symbolized Babylonian gods.
