The Uruk period levels at Susa are called Susa I (c. 4000–3700 BCE) and Susa II (c. 3700–3100 BCE), during which the site becomes an urban settlement.

Susa I sees the beginning of monumental architecture on the site, with the construction of a 'High Terrace', which is increased during Susa II to measure roughly sixty by forty-five meters.

The most interesting aspect of this site is the objects discovered here, which are the most important evidence available to us for the art of the Uruk period and the beginning of administration and writing.
