Kadıköy in the context of "Council of Chalcedon"

The Hejaz railway (also spelled Hedjaz or Hijaz; Arabic: سِكَّة حَدِيد الحِجَاز sikkat ḥadīd al-ḥijāz or Arabic: الخَط الحَدِيدِي الحِجَازِي, Ottoman Turkish: حجاز دمیریولی, Turkish: Hicaz Demiryolu) was a narrow-gauge railway (1,050 mm / 3 ft 5+11⁄32 in track gauge) that ran from Damascus to Medina, through the Hejaz region of modern-day Saudi Arabia, with a branch line to Haifa on the Mediterranean Sea. The project was ordered by Sultan Abdul Hamid II in March 1900.

It was a part of the Ottoman railway network and the original goal was to extend the line from the Haydarpaşa Terminal in Kadıköy, Istanbul beyond Damascus to the Islamic holy city of Mecca. However, construction was interrupted due to the outbreak of World War I, and it reached only to Medina, 400 kilometres (250 mi) short of Mecca. The completed Damascus to Medina section was 1,300 kilometres (810 mi). It was the only railway completely built and operated by the Ottoman Empire.

Chalcedon (/ˈkælsɪˌdɒn, kælˈsiːdən/; Ancient Greek: Χαλκηδών, romanized: Khalkēdṓn) was an ancient maritime town of Bithynia, in Asia Minor, Turkey. 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 the Maiden's 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.

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.

Osman Hamdi Bey (30 December 1842 – 24 February 1910) was an Ottoman Turkish administrator, intellectual, art expert and also a prominent and pioneering painter. He was the Ottoman Empire's first modern archaeologist, and is regarded as the founding father of both archaeology and the museum curator's professions in Turkey. He was the founder of Istanbul Archaeology Museums and of the Istanbul Academy of Fine Arts (Turkish: Sanayi-i Nefise Mektebi) known today as the Mimar Sinan Fine Arts University. He was also the first mayor of Kadıköy.

A cemevi or cem evi (pronounced and sometimes written as djemevi; meaning literally "a house of gathering" in Turkish) is a place of fundamental importance for Turkey's Alevi-Bektashiyyah tariqa populations. Certain Alevi organizations describe cemevis as places of worship, and ask for this to be officially recognized. However, the Directorate of Religious Affairs of Turkey does not recognise cemevis as Muslim places of worship, and only recognises Sunni and Ja'fari-Shi’ite mosques.
