Bet Yaakov Synagogue (Hebrew: קהל קדוש בית יעקב) is a synagogue in Istanbul, Turkey that was built in 1878. It is located at the Asian side of the Bosphorus in the area called Kuzguncuk, just beside a Greek Orthodox church. The Jewish population of Kuzguncuk having moved away, it is kept alive by worshippers whose families originated there. Shabbat services on Saturday morning are held regularly.[1]
