Jerash was laid out with one long street (Cardo) and two intersecting ones called Decumani. This Greco-Roman city was also surrounded by a wall with a south and north gate. Most of the important structures were constructed near the grid intersections. A notable exception was the Temple of Artemis seen in the background. It was built on a hill during the mid-2nd century so it was visible from almost anywhere in ancient Gerasa.
