German archaeologists, under the direction of Robert Koldeway, excavated at ancient Babylon in Iraq, between 1899 and 1917. The Procession Street ran from the Ishtar Gate to the bridge over the Euphrates River. A 250 meter [820 feet] section of the street was excavated by the German expedition. Only a short section is reconstructed in the Museum in Berlin. The section here is 30 meters [98 feet] long and 8 meters [26 feet] wide. Original fragments were used in the reconstruction. The street was originally 20 to 24 meters [54-79 feet] wide. (See Fant & Reddish, Lost Treasures of the Bible, 199-205.)
The Ishtar Gate was constructed during the reign of Babylonian king Nebuchadnezzar (605-562 B.C.). All of these lions, bulls, and dragons were excavated from the mound of ancient Babylon, and eventually taken to Berlin in 1926. Even under the Communist government of East Germany this gate was preserved. I saw it several times before the Berlin Wall came down.
The Procession Street and Ishtar Gate are reconstructed in the Pergamum Museum in Berlin, but technically, this wing of the museum is called the Vorderasiatisches Museum (Museum of the Ancient Near East).
Babylon was once the greatest city of the world when the Neo-Babylonian Empire reigned supreme in the Ancient Near East (626-539 B.C.). The prophet Daniel was active in Babylon from 605 B.C. until after the fall of the city to the Persians (The prophecy of Daniel). I can not imagine that he failed to see this gate.
Nebuchadnezzar was a megalomaniac. His pride is evident in the statement recorded by the prophet Daniel.
The king uttered these words: “Is this not the great Babylon that I have built for a royal residence by my own mighty strength and for my majestic honor?” (Daniel 4:30 NET Bible)
