The church was designed with a private entrance for the king from within the Residence.[4] The public entrance faced east, towards the Marstallplatz. Above the doorway a deesis sculpted in relief is framed by a gothic wimperg, with statues of Saint Peter and Saint Paul on either side.[5] Inside, the nave is made up of two domes and an apse, each separated by an arch of brickwork. These, like the columns that separated the side aisles and supported the gallery, were originally richly ornamented.
