This is a partly-ruined complex built as a pleasure garden by the first Sultan in 1765. One of the bathing pools was dedicated to the sultan's harem, and he had a tower overlooking the area so he could take his pick. Towards the back is the original entrance to the pools, a small dock connected to a long-since-vanished river; a bit of snooping beyond this entrance will get you to a back street, where one can visit a fascinating network of tunnels and rooms, including an Escher-like series of interlacing staircases over what looks like a disused well.
