The Ishtar Gate is the eighth gate to the inner city of Babylon. It was constructed in about 575 BC by order of King Nebuchadnezzar II on the north side of the city.
Dedicated to the Babylonian goddess Ishtar, the gate was constructed using a rare blue stone called lapis lazuli with alternating rows of bas-relief mušḫuššu (dragons) and aurochs. Originally the gate, being part of the Walls of Babylon, was considered one of the Seven Wonders of the world until, in the 6th century AD, it was replaced by the Lighthouse of Alexandria.
King Nebuchadnezzar built the Ishtar Gate in Babylon in the honor of the first Blue Djinn, but in his self-pride he also built himself a magnificant palace. This angered the Blue Djinn because he built himself a greater palace than her own, which caused him to be sentenced to the Iravotum.
