Currently, there is a lot of talk pertaining to the special needs of museum visitors, and the ways of building dedicated exhibition spaces as well as preparing sightseeing tours The lack of financial resources means that these accessibility tools cannot be fully created. Stereotypes of visitors with special needs then appear. Museum professionals try to eliminate them, which is why they increasingly include people with disabilities in the process of creating workshops, lessons, exhibitions and other museum projects. The article is an attempt at moving beyond the stereotype itself – through joint learning – to be open to others. It also provides a case study done on the example of the Museum of Engineering and Technology in Kraków that describes several years of activity and the steps taken by the museum towards improving its accessibility.
