If you've ever been to a synagogue, you'll know that they're generally quite simple and austere places of worship. But not Budapest's Great Synagogue. This Jewish temple on Dohány Street is tall and majestic, with one of the largest and most impressive cathedral naves I've ever seen. It is one of Europe's most beautiful synagogues. The Great Jewish Synagogue, built between 1854 and 1859, seats 3000 people. It is Europe's largest synagogue and the world's second-largest (after Belz Great Synagogue, in Jerusalem).
