The Ishtar Gate was constructed by the Babylonian King Nebuchadnezzar II circa 575 BCE. It was the eighth gate of the city of Babylon (in present day Iraq) and was the main entrance into the city. The Ishtar Gate was part of Nebuchadnezzar's plan to beautify his empire's capital and during the first half of the 6th century BCE, he also restored the temple of Marduk and built the renowned wonder: the Hanging Gardens as part of this plan. The magnificence of the Ishtar Gate was so well known that it made the initial list of the Seven Wonders of the Ancient World.


The Ishtar Gate is named so, because it was dedicated to the Babylonian goddess Ishtar, although Nebuchadnezzar pays homage to other Babylonian deities through various animal representations. The animals represented on the gate are young bulls (aurochs), lions, and dragons (sirrush). These animals are symbolic representations of certain deities: lions are often associated with Ishtar, bulls with Adad, and dragons with Marduk. Respectively, Ishtar was a goddess of fertility, love, war, and sex, Adad was a weather god, and Marduk was the chief or national god of Babylon.


The front of the gate is adorned with glazed bricks with alternating rows of dragons and bulls. The beasts are furnished in yellow and brown tiles, while the bricks surrounding them are blue. The blue enameled tiles are thought to be of lapis lazuli, but there is some debate to this conjecture. The gates measured more than 38 feet (11.5 m) high with a vast antechamber on the southern side.
