The Ethnographic Museum has some really impressive collections. Beside various collections showing Croatian ethnography, the museum has very valuable items collected by renown world explorers from the 19th century Brothers Seljan and Mr. Lerman. The only problem when visiting the museum (and not a small one)- all explanations are solely in Croatian. It's such a pity for such an amazing place.
