Mount Koressos Bülbül Dagi

To the southwest of the excavated area of Ephesus is the long ridge of Bülbül Dagi (Nightingale Hill 358m/1,175ft), known in antiquity as Mount Koressos, which can be climbed either on the east side or by a road ascending from the ancient harbor up the west side of the ridge. Along the ridge extends the Hellenistic town wall of the time of Lysimachos, still retaining some of the battlements.

On a hill above the harbor canal, known in Hellenistic times as Pagos Astyagou, stands a ruined watch-tower, originally on the Hellenistic town walls, which for some unexplained reason is known as St Paul's Prison.
