At the beginning of the Second World War, Buchach had 11,100 inhabitants, of whom 2,400 were Ukrainians, 3,550 Poles, and 5,150 Jews. In 1959, Buchach had 7,000 inhabitants. Such a sharp decrease in the population of the city is explained by the Nazi genocide against the Jews, the deportation of Poles to the territory of Poland and the losses of Ukrainians in the struggle against the Stalinist regime. Today, the population of the city is 12,600, the area of the city is 1,026 hectares.
The materials of the exhibition tell about the emergence and combat activities of the Ukrainian Insurgent Army in Volyn, about the commanders and insurgent soldiers, among whom was the graphic artist Nil Khasevych, whose military graphics are presented in the museum.
