The Antonin nymphaeum
Under Marcus Aurelius (161-180) AD a Nymphaeum or monumental fountain was built against an Augustan terrace wall along the northern edge of the Upper Agora. The water itself was used as an architectural element, falling like a waterfall into the central basin. The fountain was of the tabernacle type in which tabernacles or aediculae are interspersed with hollowed niches in the back wall. Each tabernacle rests on a podium and counts one or two Corinthian columns. You should know the statues are modern copies, the originals are in the Burdur museum.
