When the Arbatsko-Pokrovskaya Line was first built, the tracks from Ploshchad Revolyutsii extended westward to Aleksandrovsky Sad rather than Arbatskaya.
The spaces between the arches are partially filled by decorative ventilation grilles and ceiling tracery.
[1] Each arch is flanked by a pair of bronze sculptures by Matvey Manizer depicting the people of the Soviet Union, including soldiers, farmers, athletes, writers, aviators, industrial workers, and schoolchildren.
The series is meant to be considered in order, symbolizing Russia's transformation from the pre-revolutionary past, through the revolution, into the (then) contemporary era.
The practice is targeted at specific areas on individual sculptures, including the soldier's pistol, the patrolman's dog, the roosters, and the female student's shoe.
