The Great Synagogue on Dohány Street shows how hard many Hungarian Jews worked to integrate into the local culture. The congregation here hired a famous Gentile architect to design the building, which has a layout and façade not so different from a Christian church. While the two “bell” towers are meant to echo descriptions of the Temple of Solomon, they and the rose window are the reason the building was dubbed “the most beautiful Catholic synagogue in the world.” It’s still the second largest synagogue worldwide, after Temple Emanu-El of New York.
