The Ashkenazi Synagogue The Ashkenazi Synagogue is situated in the Karaköy neighborhood of Beyoğlu in Istanbul, Turkey, near the Galata Tower. It is the only currently active Ashkenazi synagogue that welcomes visitors for prayers. This synagogue was founded in 1900 by Jews of Austrian origin. The name "Ashkenazi" is derived from the biblical figure Ashkenaz, who was the first son of Gomer. The name Gomer has often been linked to the ethnonym Cimmerians. The biblical Ashkenaz is said to be derived from Assyrian Aškūza, an ethnic group that was exiled by the Cimmerians and later claimed Armenia in the Upper Euphrates. This synagogue was the last of three built by Ashkenazim, who make up only 4% of Turkey's Jewish population. Visitors are welcome during weekday mornings and Saturday morning services. The synagogue also hosts various events such as weddings, Bar Mitzvahs, and other religious ceremonies.
