Old New Synagogue, Czech Republic -

Prague's beautiful Alteneu Shul (Old-New Synagogue) is Europe's oldest active synagogue. The building dates back to 1270, and legend suggests that the figure of a Golem (an animated anthropomorphic being in Jewish folklore) created by Rabbi Judah Loew ben Bezalel (1526–1609) lies in the attic where the genizah (or store room) of Prague's community is kept. Fortunately, the Gestapo neglected to enter the genizah during the Nazi occupation of the city in the Second World War, thus sparing the building from destruction.
