East of the palaestra and Hadrianic Baths is an open square overlooked by the Nymphaeum, or Temple of Nymphs. Although half-collapsed and requiring considerable imagination, its superb façade of red-granite and cipolin columns was once reminiscent of the façade of Roman theatres and its niches were once filled with marble statues. The monumental fountain was added during the reign of Septimius Severus.
