History

Gemlik was the site of the ancient Greek city of Cius (/ˈsaɪəs/; Greek: Kίος or Κῖος Kios), later renamed Prusias on the Sea (/ˈpruːʒəs/; Latin: Prusias ad Mare) after king Prusias I of Bithynia, was an ancient Greek city bordering the Propontis (now known as the Sea of Marmara), in Bithynia and formerly in Mysia (in modern northwestern Turkey), and had a long history, being mentioned by Herodotus, Xenophon, Aristotle, Strabo and Apollonius Rhodius. It was strategically placed at the head of a gulf in the Propontis, called the gulf of Cius, or Cianus Sinus. Herodotus calls it Cius of Mysia; and also Xenophon, from which it appears that Mysia, even in Xenophon's time, extended at least as far east as the head of the gulf of Cius. Pliny the Elder reports that Cius was a Milesian colony. It was at the foot of Mount Arganthonius, and there was a myth that Hylas, one of the companions of Heracles on the voyage to Colchis, was carried off by the nymphs when he went to get water here; and also that Cius, another companion of Heracles, on his return from Colchis, stayed here and founded the city, to which he gave his name. Pliny mentions a river Hylas and a river Cius here, one of which reminds us of the name of the youth who was stolen by the nymphs, and the other of the mythical founder. The Cius may be the channel by which the lake Ascania discharges its waters into the gulf of Cius; though Pliny speaks of the Ascanium flumen as flowing into the gulf, and we must assume that he gives this name to the channel which connects the lake and the sea. If the river Cius is not identical with this channel, it must be a small stream near Cius. As Ptolemy speaks of the outlets of the Ascanius, it has been conjectured that there may have been two, and that they may be the Hylas and…

Geography

Gemlik was built on a plain which is bordered on three sides by mountains, with the Samanli Mountains lying from southeast to the northwest. There is a large plain spanning much of the east end of Gemlik to the coast. Karsak Stream, which originates at Lake Iznik, divides this plain and town center into two parts. The Gulf of Gemlik, often called fig port of Kilyos (in reference to the ancient name of the town), is 35 km from east to west, 10–15 km from north to south, and 100–150 meters deep. For many years, this gulf had been used for docking ships, but now it serves as a tourist attraction. The largest river in the area is Karsak, gurgles from İznik Lake and spilles to Gulf of Gemlik.
