This monumental fountain is probably to be considered in connection with the residential complex identified beneath the nearby basilica, which may be dated to the first decades of the 4th century AD. For its semicircular plan with niches surrounded by aediculae, and for the employment of reused marble, the fountain likely dates to Late Antiquity. Starting in the late 7th century AD, the abandoned Nymphaeum was filled with dumped waste. Lastly, between the late 9th and the 10th centuries AD, the building’s area was re-occupied by a burial.
