The Gallery was opened in February 1985. It became home to famous banners, spatial compositions, sculptures made of various materials, ordinary objects, often junk, which takes on new meanings in the hands of the artist. It featured metaphorical, witty, contradictory titles, that encourage reflection on the contemporary world and art. The gallery was established in the former lounging room of the “Warszawianka” sanatorium, built in 1935 according to the design by Wacław Nowakowski. The wooden lounging room had two floors, with a wall of windows from the south. The adapted spaces became multi-level interiors, serving as exhibition halls, a concert hall, as well as the artist's apartment and studio. “Hasior is a relative of late-medieval visual artists-poets”, wrote Marek Rostworowski, an art historian about the artist, “who evoke a beautiful and monstrous world combining reality with metaphor and the afterlife, intended to enchant a man tormented by reality and longing to cross it – the era of Hieronymus Bosch, Bruegel, witches or the Spanish lovers of martyrdom. (…) With him, nothing is what it is, but is what uncontrolled imagination can see. It is also a fairy tale because in Hasior's sentences words mean something different than when they are separated.”
