View looking south at the exterior of the fountain that is located on the west end of the Decumanus opposite the West Gate of the City. The Nymphaeum (monumental water fountain) is approached by three steps and the pool behind the front wall is a full semicircle. Some of the upper portions of the back of the Nymphaeum are visible.
Many larger–than–life–size statues were found both in and in front of the pool. Originally they would have decorated the pool.
Because of the statue of Caracalla (188–217 CE) that was found here, it is called the "Caracalla Nymphaeum."
