Dating from the mid-13th century, this is the oldest functioning synagogue in Europe and one of the most important works of early Gothic in Prague. The name refers to the legend that the synagogue was built on the site of an ancient Jewish temple, and the temple's stones were used to build the present structure. Amazingly, the synagogue has survived fires, the razing of the ghetto, and the Nazi occupation intact; it's still in use. The entrance, with its vault supported by two pillars, is the oldest part of the synagogue. Note that men are required to cover their heads inside, and during services men and women sit apart.
