The southwest wing had to be made shorter since the Storkyrkan was in the way. This asymmetry, created by the different lengths of the wings, was compensated by adding the two detached, semicircular wings for the Royal guards and the Commanders, west of the main building. These wings encircle the courtyard. Tessin's plans and commissions to artists still characterizes the facades, walls and stone pilasters as well as walls, floors, pillars and pilasters inside the palace, such as in the Hall of State, the Royal Chapel and the stairwells.
