Together with the Kunsthalle Darmstadt, the Darmstädter Sezession is developing an experimental format as part of the festival «Den Bogen Spannen – Darmstädter Sezession 1919 bis 2019». During the reconstruction of the Kunsthalle`s forecourt in August and September 2019, the experiment will take advantage of the special situation and address it for one month. How can we deal with necessary phases of interruption constructively? Perhaps the seed of Peter Weiss´dream of reconciliation between workers and art is sown in the construction site? The arc is streched from the building site to the artist´s studio, from work to art, from spirit to shovel and from the White Cube into the ground.
