Smolenskaya has square, white marblecolumns with fluted corners, decorative cornices, and ventilation grilles concealed behind ornamental sconces. At the end of the platform is a bas-relief by G.I. Motovilov entitled "The Defenders of Russia," which depicts soldiers of the Red Army in battle. The architects of the station were Igor Rozhin and G. P. Yakovlev. At 50 m below the surface, Smolenskaya was the deepest station on the line until Park Pobedy opened in 2003.
