Regional history or portrait art?
The Museum of Eastern Bosnia covers archaeology, ethnology, history, natural heritage and art. Choose it when you want the story of north-eastern Bosnia beyond Tuzla’s salt production. Look at its current exhibitions to see what will be on during your stay.
The International Portrait Gallery has an Ismet Mujezinović collection and an associated atelier, giving visual art a particular local connection. The listed gallery address is 2 tuzlanske brigade 13. Its visitor listing gives weekday hours of 07:30–16:00 and contacts for group visits on weekdays or weekends. A weekend group visit needs that arrangement; the listing does not promise ordinary walk-in weekend opening.
With one day, put the squares and one of those visits together. With two, the other institution can give the second day a purpose outside the bathing season. Check current exhibitions and admission arrangements with each venue.
