This misunderstanding cannot be called a museum. Just a set of not particularly interesting items that are not connected by a common line. A completely uninteresting and very small exposition, it is not worth wasting time on it. Although you can spend half an hour with a leisurely inspection, if you don't mind 8 rubles per ticket. But in general it should be a pity because the price is very much overstated.
Positive reviews seem to be from those who have never been to museums.
The Museum of the city's history is organized in a historic mansion built in 1820-22, which served as the summer residence of Count N.P. Rumyantsev. The mansion is small, the museum reveals only some pages of the history of Gomel. The expositions are interesting, well filled with exhibits and necessary information.
