Jubilee Synagogue (Czech: Jubilejní synagoga), also known as the Jerusalem Synagogue (Czech: Jeruzalémská synagoga) for its location on Jerusalem Street, is an active synagogue in Prague, Czech Republic. It was built in 1906, designed by Wilhelm Stiassny and named in honor of the silver Jubilee of Emperor Franz Joseph I of Austria. Although originally built as a "reform" synagogue (with an organ and a choir), it is nowadays used by the more traditional ("modern orthodox") members of the Prague Jewish community, aligning itself officially with orthodox Judaism. Still, compared to the famous other active synagogue of Prague, the Old-New Synagogue, the Jubilee Synagogue is far less stringent in many ways.
