View looking east at the interior basin of the fountain that is located on the west end of the Decumanus opposite the West Gate of the City.
On the left is the outer wall of the Nymphaeum, and below it a water-collecting channel. Note also, the basin that interrupts this wall. The large collecting basin is a semicircle, 21 ft. in diameter. On the lower portion of the curved back wall pieces of marble tile are still attached to the wall. In addition, 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."
