The Maalem Synagogue is a Jewish congregation and synagogue, located on Harap Çeşme Street, on the slopes overlooking the Golden Horn, near the Jewish old age home in the Hasköy district of Istanbul, Turkey.
It is the only remaining open synagogue in an area that once had many Jewish residents. Completed in the early 20th century, the synagogue is open, yet only open for Shabbat services.[2]
