The Ethnographic Museum is a great spot to get a better feel for Balkan culture and its diversity. Overall, I was really impressed with the exhibits, especially since it only cost 60 dinars, or $1, to get in.
The material housed in the museum ranges from clothing and tableware to house styles and farming/herding equipment. Although not all artifacts are labeled, there are a number of interpretive signs (in English and Serbian) throughout the museum that add context to what you are observing.
The first floor of the museum is dedicated to textiles and clothing styles of the late 19th and 20th centuries from across "Serbian" regions. Even after living in Serbia-Montenegro for the past year and consistently hearing about the diversity of clothing styles, it wasn’t until I saw this exhibit with all the different styles by region that I began to understand the true diversity of dress.
The second floor is predominantly a weaving exhibit. It highlights the various raw materials used, how and with what they were dyed, standard weaving equipment, and what types of items were produced and their significance in society. The third floor was devoted to the household. Exhibits highlighted the geographical and economic differences of "Serbian" regions and how those differences structured the cultural materials from each area.
Overall, this was great. It is not the most sophisticated museum, but it does an excellent job at providing a fundamental glimpse at Serbian, or more generally, Balkan culture. And the truly great thing is that it is open every day, even Sunday.
