Kadıköy, on the Asiatic shore and across the Bosphorus from what was once Byzantium and is now European İstanbul, claims in legend to be older than Byzantium. Byzantium’s founders looked down on it, saying that those who had settled there were blind to have ignored the better site in Europe. However, many of its residents have preferred to live here because it is in Asia and therefore is closer to the holy city of Mecca.
The Church of St. Euphemşa (probably located somewhere near the crossroad of Altı Yol) was the location of the Fourth Ecumenical Council (the Council of Chalcedon) in 451. This Council brought the decision against the Monophysites which divided the Armenian and Syrian Orthodox churches from the Latin (Roman) Catholic and Eastern (Greek) Orthodox Stones from the ruined building were used in the 16th century in the Mosque of Süleyman the Magnificent in Istanbul.
Present-day Kadıköy is a bustling metropolis with an almost carnival atmosphere among its residents.
