Originally build as a Yugoslav army barracks in 1935, this stone building now is the National Art Gallery of Kosovo. Despite its name, you should not expect to find any Albanian national art here: this space is mostly used for local and international contemporary and visual art.
The gallery has got an excellent space, with white walls and unique grey marble flooring. The building was transformed from a stone army barracks to an exhibition space in 1983, and it has since been used for different exhibitions, for both private and national purposes.
The most notable work in this building is that of Musli Mulliqi in my opinion. He was an excellent expressionist painter from Kosovo, and his work is pretty hard to find outside here.
The gallery occasionally hosts nice events with free wine and cheese, so it is best to check their Facebook page for updates. It is definitely worth a visit, especially since it is located just behind the National Library.
