The Jewish community of Novi Sad was allowed to build its first synagogue in the early 18th century. This first synagogue building was followed by three others that were erected one after another and served the local community during the 18th and the 19th centuries. In the Last decade of 19th century the fourth synagogue became too small to fulfill the needs of growing Jewish community. So the plans were made for building the fifth one. It was suppose to be the major project for entire Jewish community, under the leadership of Dr. Karl Kohn, its long time president. The complex were to be large, and as beautiful as the well known architect could make it, and in my opinion he did hell of a job 
So the story of our, The fifth on tht location, synagogue started back in 1905. with the start of its constructions that were finished only four years later. The Hungarian-born Jewish architect Lipot Baumhorn (1860-1932), at the time widely regarded as the leading synagogue architect in the Austro-Hungarian Empire was choose for the lead architect. The complex had to include, on both sides of the synagogue, two buildings decorated in a similar pattern. One building sheltered the offices of the Jewish Community and the residences specially built for the synagogue officials, while the second building served the Jewish school (and today it`s the well-known ballet school). It presents the monument of Hungarian secession, the typically Hungarian style that combines Art Nouveau elements with ideas taken from the previously dominant Historicism style of architecture. The design strongly resembles the architecture of medieval churches: it follows a cruciform plan made up of a central nave with an apse on the east side crossed by a transept. The synagogue building is crowned by a large and high cupola that still dominates the other buildings in the neighborhood. The cupola is supported by buttresses and rises over an octagonal basis that has a row of eight windows, each divided into three lights, serving as a lantern for the prayer hall below. The exterior walls of the synagogue, with the exception of the eastern one, are each dominated by a porch above which there is a rose window with stained glass. The western facade is flanked by two symmetric towers with smaller octagonal cupolas and boasts the largest porch. Smaller circular oculus windows decorate the towers of the western facade and the upper level of the apse. The eastern wall has, in addition to a prominent apse, two smaller apses that continue the lateral aisles of the nave. The western facade and the southern and northern walls are decorated with the two Tablets of Law with inscriptions in Hebrew. This is the only typically Jewish motif visible from the outside of the building.
As for the interior of the synagogue, it is arranged in a manner common amongst liberal synagogues of the second half of the 19th century. The bimah is located close to the Holy Ark, at the eastern end of the prayer hall; there are rows of benches in the lower floor as well as in the two lateral balconies reserved for the women section. The prayers at the synagogue of Novi Sad were lead by a cantor accompanied by an organ, a mixed choir, and occasionally also soloists.
Inside and out, it was built to last and serve the whole community. Magnificent complex that shows the optimistic attitude of Jews, that enthusiastically adopted Hungarian identity.
Then the Second World War came. Only about a quarter of the more than 4,000 Jews of Novi Sad survived the Holocaust that followed the German invasion of Yugoslavia in 1941 and the annexation of Novi Sad to Hungary. Over 800 Jews of Novi Sad were murdered during massacres conducted by the Hungarian police against Jews and Serbs in January 1942. In May 1944. the synagogue of Novi Sad served as an arrest house for the Jews of Novi Sad and it was from there that they were deported to the Nazi extermination camps. The building of the synagogue, although desecrated and robbed of many valuable items, suffered only light damage. The synagogue was consecrated again in 1945. when it became the center of the revived Jewish life in the city and sometimes been used by Holocaust survivors in the years after the Second World War. In the 1950's many members of the local community chose to immigrate to Israel.
During the 1970's the small number of Jewish worshipers left in Novi Sad used to pray in the offices of Jewish community, and used the synagogue only for the High Holidays. As the community no longer could support the costs of maintenance, in 1991. the synagogue building was leased to the city for a period of twenty five years. Taking advantage of the fine acoustics of the synagogue building, the city , having restored the interior, decided to use it as a concert hall for classic and other music performances. The Jewish community was able to use the synagogue whenever it wishes as they did each year for celebrating major Jewish holidays. The adjacent building that formerly housed the Jewish school is now home to a ballet secondary school.
Located in Jevrejska (Jewish) Street, close to the city center, ever since it`s building the synagogue has been recognized as a landmark of Novi Sad. Evan tho today the synagogue is not being used for religious purposes, due to it`s acoustics it is often used as a concert hall. Those events are known as pretty epic and they attract a great deal of Novi Sad residents as well as tourists and they are a good chance to remember the history of this wonderful complex, become familiar with its interior and be blown away by its acoustics and beauty. I encourage you greatly to visit one of them if you happen to be in the city when they take place (for example I highly suggest Hearts in Harmony concert- really spectacular concert with a popular theme- Inclusion- that takes place, now traditionally in the Synagogue, in the middle of June)
