Chalcedon
Chalcedon ( or ;
, sometimes transliterated as "Chalkedon") was an ancient maritime town of Bithynia, in Asia Minor. It was located almost directly opposite Byzantium, south of Scutari (modern Üsküdar) and it is now a district of the city of Istanbul named Kadıköy. The name "Chalcedon" is a variant of Calchedon, found on all the coins of the town as well as in manuscripts of Herodotus's "Histories", Xenophon's "Hellenica", Arrian's "Anabasis", and other works. Except for a tower, almost no above-ground vestiges of the ancient city survive in Kadıköy today; artifacts uncovered at Altıyol and other excavation sites are on display at the Istanbul Archaeological Museum.
Sigeion
Sigeion (Ancient Greek: , "Sigeion"; Latin: "Sigeum") was an ancient Greek city in the north-west of the Troad region of Anatolia located at the mouth of the Scamander (the modern Karamenderes River). Sigeion commanded a ridge between the Aegean Sea and the Scamander which is now known as Yenişehir and is a part of the Çanakkale district in Çanakkale province, Turkey. The surrounding region was referred to as the Sigean Promonotory, which was frequently used as a point of reference by ancient geographers since it marked the mouth of the Hellespont. The outline of this promontory is no longer visible due to the alluvial activity of the Karamenderes which has filled in the embayment east of Yenişehir. The name 'Sigeion' means 'silent place' and is derived from Ancient Greek ("sigē"), 'silence'; in Classical Antiquity, the name was assumed to be antiphrastic, i.e. indicating a characteristic of the place contrary to reality, since the seas in this region are known for their fierce storms.
