Many mistakenly believe that only Red Guards who died during the Czechoslovak Corps uprising are buried in the mass graves at the Monument to the Fighters of the Revolution. This is not entirely true.

On May 30, 1918, when the soldiers of the Czechoslovak Corps joyfully moved east, Penza was just beginning to count its losses. It turned out that more than 300 people died during the defense of the city, of which 128 were soldiers of the revolutionary Czechoslovak regiment. Additionally, dozens of random townspeople died, mostly from stray bullets and shrapnel. At that time, burials were conducted at the now-closed Mitrofanievsky and Mironositssky cemeteries. However, the Penza authorities proposed an unusual solution: to create their own Red Pantheon, similar to the Kremlin Wall. The location was chosen in the historical center of the city. But not only fallen Red Army soldiers were brought to the mass graves; in the general chaos, the deceased from all over Penza were brought to Soviet Square. As a result, alongside soldiers, those who died from diseases were also buried here. Later, this site also became the resting place for shock workers of socialist labor and notable revolutionary figures of Penza.

The last burial at Soviet Square took place in 1934. The ashes of the provincial prosecutor Marshan are sealed in the Monument to the Fighters of the Revolution.
