I wouldn't have expected to find such a rich piece of European Jewish heritage in Old Town Dubrovnik, but here it is: the second oldest synagogue in Europe! There is a modest entry fee to see the small museum and the synagogue itself. The museum is composed of old Jewish artifacts and garments (very interesting) and WWII items from then-Ustasa Croatia. The man taking up the entry fee gave me a brief explanation of the museum and explained how a synagogue functioned. It was brief, fun, and informative. I'm glad I went.
