The Nymphaeum is a partially preserved Roman public fountain in Amman, Jordan.

It is located a short distance from the Hashemite Plaza, the Roman Theater and the Odeon, at the crossing of Ibn al-Atheer and Quraysh streets in al-Balad.

Such fountains were very popular in Roman cities, and Philadelphia, as Amman was known by ancient Greeks and Romans, was no exception.

[1] This nymphaeum is believed to have contained a 600-square-meter (6,500 sq ft) pool which was three meters (9.8 ft) deep and was continuously refilled with water.

[2] The nymphaeum was built in the 2nd century CE, during the same period as the nearby theatre and odeon.
