Balat is the shore of Golden Horn in the Fatih district of İstanbul. The Sephardic Jows who expelled from Spain were accepted with open arms by the Ottomans and setted in same part of the city. Balat became a centre for the regilious minorities of İstanbul. There, mosques, churches and synagogues can be seen side by side as if a living proof of the praternity of religion. Sultan Mehmet the Conqueror granted privileges to the Christian and Jewish rituals free of intervention. Those priveges are considered to be fine examples of Ottoman tolerance, and helped to keep the Christian community in the city.
