A hundred years ago, the baroque Neues Palais in the Sanssouci park, Potsdam, Germany, became a museum. Today's visitors are almost completely unaware that beyond palatial interiors, the rooms continue, hidden from sight, and have long served as workshops, offices, or depots. As part of a comprehensive restoration of the castle, this activity has now been moved elsewhere. This represents a major turning point for the Neues Palais.
