You’ll have to ignore the setting as it is found in a seriously dilapidated building, but the Museum of Eastern Bosnia is a detailed exploration of this often-forgotten part of the country. The entire spectrum of time is covered, from archeological findings to the conflict at the end of the 20th century, showcasing thousands of years of continuous life in this part of the world. The opening hours can be a little inconsistent, so maybe give them a call before you visit.
