The dovetail crenellation is interrupted by turrets at the axes of the side wings and at the corners of the central part of the building, with terracotta trophy sculptures positioned inside their alcoves. Allegoric representations of military virtues made of sandstone are featured on and in front of the facade, created by Hans Gasser, one of the most influential sculptors of his time. Just below the round windows, the female figures (from left to right) represent strength, vigilance, piety, and wisdom; next to the three openings leading to the lobby are four male figures, which stand for bravery, loyalty to the flag, self-sacrifice, and military intelligence.
