Street art takes over the Wien Museum all summer long Before its renovation, the 2,000 square metres of the "old" Wien Museum have been converted into an arena for street art and skateboarding. The museum took the opportunity to have its interior designed by Viennese street art artists. In addition to classic graffiti and metre-high murals, there are also photo exhibitions, a do-it-yourself area with workshops and a skate park. The exhibition will last all summer long until the 1st of September and admission is free.
