The Spanish Synagogue in Prague is beyond beautiful. Decorated in the Moorish Revival Style at the end of the 19th century, the attention to detail is exquisite. Even though I spent well over an hour there, which normally is amply sufficient for a building that size, I had the feeling that there were many more motifs and designs left for me to discover, and I had a hard time leaving. This is but a small sampling, but a feast to the eyes nonetheless.
Spanish Synagogue seems pretty popular today!
