Istanbul Fatih district, which was named after Sultan Mehmed the Conqueror (Turkish: "Fatih Sultan Mehmed"), corresponds to what was, until the Ottoman conquest in 1453, the whole of the city of Constantinople (today is the capital district and called the "historic peninsula" of Istanbul) on the southern shore of the Golden Horn, across the medieval Genoese citadel of Galata on the northern shore. The Genoese fortifications in Galata were largely demolished in the 19th century, leaving only the Galata Tower, to make way for the northward expansion of the city. Galata (Karaköy) is today a quarter within the Beyoğlu (Pera) district,
Beyoğlu Her room is conserved as a museum. S. Antonio di Padova, the largest Catholic church in Turkey, and the Neve Shalom Synagogue, the largest synagogue in Turkey, are also in Beyoğlu. There are other important Catholic and Orthodox churches in the area, such as the Saint Mary Draperis church or centrally located Hagia Triada Church at the conjunction point between Istiklal Avenue and Taksim Square. It is the seat of the Chaldean Catholic Archeparchy of Diyarbakir. The only Jewish Museum of Turkey, which has been converted from a synagogue, is located in the Karaköy quarter, which was known as Galata
