Interior of the Klausen synagogue, 1694, Jewish quarter (Josefov), The Klausen Synagogue is nowadays the largest synagogue in the former Prague Jewish ghetto and also a single example of an early Baroque synagogue in the area. Today the synagogue is administered by the Jewish Museum in Prague. In 1570s a renowned businessman and benefactor of the ghetto, Mordechai Maisel, decided to build in the area of the present Klausen Synagogue a complex of buildings, probably including synagogues and a private Talmudic school.

Many important rabbis, for example Eleazar Fleckeles, are also connected with the synagogue. In 1883–84, the synagogue was reconstructed by an architect Bedřich Münzberger, who also partook in decorating the Spanish Synagogue.
