 The oldest district in Izmir, Kemeralti dates back to Roman times and is home to the densest concentration of Jewish landmarks in all of Turkey.The six mosques surrounding the synagogue complex evince the centuries of peaceful co-habitation among the local Ottoman and Jewish communities.A heritage organization, the "Izmir Project" (planned and partly funded by the Mordechai Kiriaty Foundation, the Izmir-Konak municipality, the Izmir Sephardic Cultural Heritage Association (ISCHA), and the American Friends of Izmir Jewish Heritage Museum) calls Izmir "the only city in the world in which an unusual cluster of synagogues bearing a typical medieval Spanish architectural style is preserved."
