The first evidence of a planned city at Ephesus [Ephesos] dates from the Hellenistic period, when the site was moved. Its new layout was based on a Hippodamic grid, in which some older street courses such as 'Kouretes Street' (Embolos), were preserved. The Embolos was part of a procession road around the Panayirdag Hills to the Artemision. It took its name from the class of priests referred to as 'curetes.' Colonnaded galleries with mosaics on the floor were located on both sides of the street with a roof to protect the pedestrians from sun or rain. There were also fountains, monuments, statues and shops on the sides of the street. The shops on the south side were two-storied.
