I reflect about the absence of Net Art in traditional museums of art in Portugal. I present the interesting case of Museu do Chiado – the National Museum of Contemporary Art (MNAC) first website and the online gallery Site- Specific created along with it, in the early 2000s. I then provide a context to the initial technoculture environment in the country and problematise the “gap of institutional invisibility” that the only interactive and generative artwork commissioned by the museum has fallen.
