Старонова синагога в Праге, 1270 г. Старейшая действующая синагога в мире.
The synagogue was originally called the New or Great Synagogue and later, when newer synagogues were built in the 16th century, it became known as the Old-New Synagogue. Another explanation deviates the name from the Hebrew עַל תְּנַאי (al tenay), which means "on condition". According to legend angels have brought stones from the Temple in Jerusalem to build the Synagogue in Prague - "on condition", that they are to be returned, when the Messiah comes, i.e. when the Temple in Jerusalem is rebuilt and the stones are needed.
