Not all MACBA’s walls are part of the original building. In particular, the plasterboard wall that rises in the atrium of the building (at the very entrance to the Museum), and which joins two structural pillars, is an intervention by the artist Luz Broto. In parallel with the exhibition of the MACBA Collection, ‘Poetic Intention’, the artist installed an aluminium guide on the floor between two of the building’s pillars, and has been gradually extending the wall upwards ever since. Initially just a drawing, it is now a physical structure connecting the three floors of the building: from the base, on the ground floor, to the ceiling on the second. A wall that will continue to grow until, when the exhibition closes, it will prevent access to the rooms on the first and second floors of the Museum. The proposal stems from an intervention that the artist made in 2021 at the ethall gallery in Hospitalet del Llobregat (Barcelona). Here, Broto built four plasterboard walls, extending the eight pillars of the exhibition area, and altering the space of the gallery. She also provided the project drawings and some pencils for whoever wanted to sign a contract with the artist to build a new wall in another space. A message that appealed to Elvira Dyangane Ose, Director of MACBA, when she visited the exhibition. Come and see the result.
