Casa da Arquitectura and the Liminality of Architecture Centers: Archives, Exhibitions, and Curatorial Strategies in the Digital Shift

This study explores the evolving role of architecture centers in the digital age by analyzing the case of Casa da Arquitectura (CdA) in Matosinhos, Portugal, a hybrid institution that functions as both archive and museum. Positioned within the broader context of museum digitization and liminality theory, the research investigates how CdA navigates the spatial, social, and procedural shifts inherent in digital transformation. Drawing on qualitative methods, including in-depth interviews with key personnel and on-site observations, the study examines the institution's strategies in acquisition, curation, and exhibition design. The findings highlight CdA's innovative approach to archival visibility, the creation of a multipurpose digital platform ("edif & iacute;cio digital"), and the integration of archival acquisitions with exhibition practices. These practices illustrate a condition of triple liminality of the digital museum concerning its process, position, and place. The study also discusses how digitization reconfigures the museum's organizational model in terms of accessibility and curatorial complexity. By analyzing CdA's operational and curatorial choices, the paper discusses how digital museums can act as speculative, process-oriented spaces that challenge traditional boundaries between archive and exhibition, physical and virtual, institutional and public.
