The exhibition presents a forgotten theme of the contemporary Polish history: destruction of Zwoleń by the invading German army in the beginning of September 1939. Zwoleń, like Wieluń a week earlier, was bombarded by German air forces and artillery. The town suffered heavy losses in its building (reaching 80%) and population (approximately 100 killed, number of wounded is not known).
The 80th anniversary of this traumatic events gives opportunity to commemorate them. The exhibition is mainly iconographic and includes original photos, graphics, documents, Polish and German military equipment; nevertheless the most important among artifacts are relations delivered by the eyewitnesses.
