An exhibition on architecture where the building becomes the art? The front of Bratislava, The Slovak National gallery, has been converted into what looks like a four lane highway, suspended precariously over the footpath. The classic brutalist facade of the gallery used to be concealed behind a big billboard advertising Ford. NL Architects decided if they had to have advertising on the building, they were going to do it in style. This transformation was designed as advertising for Modernice!, an exhibition of work by Dutch firm, NL architects. The exhibition is displayed in a in a fifty-meter long arm of the Bratislava museum and runs until June 21.
