Instead, there are side corridors where the women stand to view the services through narrow slits in the wall. The Old New Synagogue, also called the Altneuschul, situated in Josefov, Prague, is Europe's oldest active synagogue. The Old-New Synagogue is the oldest site of Prague’s Jewish Town and the oldest extant synagogue in Europe. In Orthodox Synagogues, the men and women are segregated and only the men are allowed in the main hall. It is probably from 1716. The interior decoration of the Old-New Synagogue is complemented by a high banner, a historical flag of the Prague Jewish community above with a symbol of the Jewish ghetto. It has been the main synagogue of the Prague Jewish community for more than 700 years. It is probably from 1716. The Old-New Synagogue is a single story building, so the women's galley is not upstairs, as is customary. The other examples of this type were the late twelfth-century synagogue in Worms (destroyed in 1938), the early thirteenth-century synagogue in Regensburg (destroyed in 1519), and the fourteenth-century Old Synagogue in Vienna (destroyed in 1420). It is also the oldest surviving medieval synagogue of twin-nave design. Today it is the oldest surviving Gothic medieval double-nave synagogue. Completed in 1270 in gothic style, it was one of Prague's first gothic buildings.
