The design of the stair hall is intended to contrast with the austere feel of the main entrance.  It features free standing Ionic columns in green scagliola which carry a frieze crowned by an anthemion cornice. The Ionic order is based on that at the Erechtheion which links the design back to the design of the entrance portico.  The richly coloured ceiling with its vigorous diagonal coffering is intended to lure the visitor up the stairs to the main level of the galleries. The graceful bronze banisters sport cast anthemion ornament and recall the staircase at The Altes Museum, a gallery open to the public, designed by Schinkel in 1832 in Berlin, to house The German Royal Collection.
