Jewish heritage in Azerbaijan is represented by several monuments in Baku, Quba, Oghuz, Ismayilli, and other parts of Azerbaijan. Many ruins of ancient synagogues have been found in different parts of the country. Jews have lived in Azerbaijan for centuries, but their arrival in Baku dates to the 1830s. Later, the community grew rapidly during the Oil Boom, which enticed diverse people to the city in search of work and wealth. Currently, there are six synagogues in Azerbaijan: two in Baku, two in Quba, and two in Oghuz. A new Jewish synagogue, which became one of the biggest synagogues in Europe opened in Baku on March 9, 2003. The main Jewish heritage sites that operate to date in Azerbaijan are the following: Synagogue of Ashkenazi Jews, Synagogue of Mountain Jews, “Alti Gumbaz” Synagogue Gilaki Synagogue, “Ashagi Mahalla” Synagogue, “Yukhari Mahalla” Synagogue, The Museum of Mountain Jews.
