The Great Synagogue (aka, Dohány Street Synagogue) in Budapest is the largest synagogue in Europe (and 2nd largest in the world). We stumbled upon it while strolling around Budapest on an autumn day and were taken back by its architectural design and unusual colorful exterior.
Originally built in the mid-19th century, the synagogue was destroyed by Nazi and Allied bombings during World War II. After the end of the Cold War, the synagogue was reconstructed over the course of a decade with the help of private donations. Today, you can see the Great Synagogue restored to its original glory and in use for its original purpose.
