Pergamon
Pergamon lies on the north edge of the Caicus plain in the historic region of Mysia in the northwest of Turkey. The Caicus river breaks through the surrounding mountains and hills at this point and flows in a wide arc to the southwest. At the foot of the mountain range to the north, between the rivers Selinus and Cetius, there is the massif of Pergamon which rises 335 metres above sea level. The site is only 26 km from the sea, but the Caicus plain is not open to the sea, since the way is blocked by the Karadağ massif. As a result, the area has a strongly inland character. In Hellenistic times, the town of Elaia at the mouth of the Caicus served as the port of Pergamon. The climate is Mediterranean with a dry period from May to August, as is common along the west coast of Asia Minor.
Pergamon
The upper terrace measured 150 x 70 metres square, making it the largest of the three terraces. It consisted of a courtyard surrounded by stoas and other structures, measuring roughly 36 x 74 metres. This complex is identified as a palaestra and had a theatre-shaped lecture hall beyond the northern stoa, which is probably of Roman date and a large banquet hall in the centre. Further rooms of uncertain function were accessible from the stoas. In the west was a south-facing Ionic antae temple, the central sanctuary of the gymnasium. The eastern area was replaced with a bath complex in Roman times. Further Roman baths were constructed to the west of the Ionic temple.
