Accessibility as a Shared Cultural Responsibility: The <em>Entre Luces</em> Project at the Pablo Gargallo Museum

In the context of the evolving role of museums as social agents, the Entre Luces project, developed at the Pablo Gargallo Museum in Zaragoza, stands out as a notable example of accessibility conceived as a shared cultural responsibility. This study investigates the co-design of a multisensory space within a listed historic building, aimed at fostering the inclusion of people with disabilities. Adopting a qualitative and participatory research approach inspired by bottom-up methodologies, the study combines document analysis, participant observation, and semi-structured interviews with museum professionals, technicians, educators, and users. Central to the process was the active involvement of individuals with disabilities, who were engaged not merely as beneficiaries but as co-authors of the design process. The findings highlight a significant transformation in museum practices and the implementation of inclusive educational pathways, enabled also through collaboration with vocational craft students. Despite operating on a small to medium scale, the museum has developed strategic indicators to assess the social and cultural impact of the project. Entre Luces is proposed as a transferable model for cultural institutions seeking to embed inclusive design within their institutional identity.
