Chalcedon

Chalcedon (; Ancient Greek: Χαλκηδών, romanized: Khalkēdṓn) was an ancient maritime town of Bithynia, in Asia Minor. It was located to the south of Chrysopolis (later known as Scutari, modern Üsküdar) and almost directly opposite Byzantium across the Bosporus strait, in Europe. At present, it is a district of the city of Istanbul named Kadıköy.
