MNAC Barcelona Expansion to Connect Historic Buildings via Underground Passage

The Museu Nacional d'Art de Catalunya in Barcelona is undergoing an expansion designed by HArquitectes and Christ & Gantenbein. The project will integrate the Palau Victòria Eugènia into the museum complex through renovation and a subterranean link with the Palau Nacional. Rather than constructing a new building, the intervention creates a continuous pathway between the structures, expanding exhibition space and improving urban integration. The expansion is scheduled for completion in 2029, coinciding with the centenary of Montjuïc's 1929 International Exhibition. This approach contrasts with iconic architectural additions, focusing instead on connecting existing buildings to enhance the cultural district.
