Beyoğlu (Turkish pronunciation: [ˈbejoːɫu]) is a district located on the European side of İstanbul, Turkey, separated from the old city (historic peninsula of Constantinople) by the Golden Horn. It was known as Pera (Πέρα, meaning "Across" in Greek) during the Middle Ages, and this name remained in common use until the early 20th century and the establishment of the Turkish Republic.
