This small nymphaeum is situated to the west of the Synagogue (IV,XVII,1). It was discovered in 1961. Walls of opus mixtum (black on the plan) belong to the first half of the second century AD. In room 5 reinforcing walls were added (red). Collapsed masonry seems to belong to a cross-vault. The nymphaeum proper is in room 6, with a small niche in the back wall, flanked by small steps.
The northern part (rooms 1-4, not on the plan; identical to room K of the Synagogue) consists of a vestibule with two columns and of a room with niches and staircases. It may have been a water reservoir.
