You are in a room that is directly adjacent to the Town Hall tower, where works by artists for whom it was important to analyse the structure of the construction of the world are exhibited. Jonasz Stern's Moment of Light is part of an individual series of works in which the surviving remnants of existence, arranged in display cases, directly testify to the passing of time, thus alluding to the Holocaust and at the same time becoming an attempt to save what remains in art. Lech Kunka's Composition, on the other hand, is one of the works in which the artist created plastic arrangements from jar and can lids, which allowed him to extract a new plastic quality from man-made objects and to express his own commentary on the reality of 1960s Poland. The paintings on display are complemented by a set of sculptures, of which Partisan by Stanisław Horno-Popławski stands out, whose deep expression is emphasised not only by the rawness of the granite, but mainly by the sculptor's giving it a state in which what is barely suggested becomes obvious to the viewer.
