It's a good museum. It tells about different historical epochs of the city of Brest. There is also a nature museum in the building. We visited together with a child of 8 years old, we were satisfied
A very interesting local history museum, I recommend you to visit. It is divided into two halls, the first one tells about the nature, flora and fauna of the Brest region, and the second hall about the history.
A wonderful museum. Rich exposition. One thing spoiled the impression: all (!) signatures are only in Belarusian. Everything seems to be clear, but it's uncomfortable, as if you're solving a riddle. It would probably be enough to hang an information stand in each hall at the entrance, where it is written in Russian what is presented in the hall.
