Chalcedon
The site of Chalcedon is located on a small peninsula on the north coast of the Sea of Marmara, near the mouth of the Bosphorus. A stream, called the Chalcis or Chalcedon in antiquity and now known as the Kurbağalıdere (Turkish: "stream with frogs"), flows into Fenerbahçe bay. There Greek colonists from Megara in Attica founded the settlement of Chalcedon in 685 BC, some seventeen years before Byzantium.
Pelion (Chaonia)
Pelion, also Pellion or Pelium (), was a fortified settlement of the Chaonian tribe of Dexaroi. One possible candidate for its location is Gorna Gorica (previously known as Goricë e Madhe), in Albania, on the ancient border between Epirus and Illyria. Another candidate for Pelion is the present-day Selcë e Poshtme where the monumental royal tombs can also be found. Pelium later served as a Macedonian border fortress. Sometime in 335 BC, just before the battle of Pelium, it was occupied by Dardanians, led by Cleitus of Dardania, who fought along with Glaucias of Taulantii against Alexander the Great.
