The Old-New Synagogue situated in Josefov is Europe’s oldest active synagogue and the oldest surviving medieval synagogue. With a twin nave design and five-ribbed vaulting of the main hall, this building represents a unique architectural style. Completed in 1270 in Gothic style, it was one of Prague’s first Gothic buildings. A still older Prague synagogue, known as the Old Synagogue, was demolished in 1867 and replaced by the Spanish Synagogue. This synagogue should definitely be on your list while exploring the Jewish Quarter. Just next to the synagogue is the Jewish Town Hall, the seat of the Chief Rabbi.
