Sinagoga di Roma
The Synagogue of Rome is one of the largest temples in Europe. It was built between 1901 and 1904 in the Jewish ghetto area of Rome. The Temple was erected between the two symbols of Roman freedom, the Capitol and the Gianicolo, emblem of the Risorgimento battles. The Synagogue can be visited only on days dedicated to worship, on Saturdays and Sundays. It's definitely worth a walk and visit it.
