Today it is used as exhibition space and since 2010 it has been collaborating on exhibitions devoted to historic photography with the Jeu de Paume in Paris.Currently it is displaying photographs of Nicolás Muller (1913-2000) under the title of 'Traces of Exile' until 31 May 2015
It also exhibits paintings and other art forms. Along with the photographs we also got to see the works of Dominik Deniau ''Exposition des Âmes' (until May10th) plus paintings by Patrick Deutschmann (until April 24th). Entry is free.
I was actually more interested in the fabric of the building but other than the staircases it offered little.
