Babylon is today famous mainly for its size and architecture from the period of Nebuchadnezzar 2 in the 6th century BCE, when it covered about 10 km² and was by far the largest city in the world. But this city only survived for few decades before it was sacked by the Persians.
Babylon’s ziggurat was most probably the historical foundation for the Biblical legend of the Tower of Babel. The ziggurat was a temple tower that rose in stepped stages, which must have appeared to be very impressive in its time, even if it hardly exceeded 50 metres. Another important architectural contribution from Babylon was the hanging gardens, counted as one of the Seven Wonders of the World in antiquity.
