The Soviet Military Cemetery (Polish: Cmentarz Mauzoleum Żołnierzy Radzieckich) in Warsaw is the burial place of 21,668 soldiers of the 1st Byelorussian Front who died fighting Nazi Germany during battles for Warsaw in 1944-1945. Their ashes scattered around the city were exhumed in 1949 and taken to this cemetery.

With an area of 19,2 ha (or 16,50 ha), the Soviet Military Cemetery is the largest Soviet war cemetery in Poland. The scupltures and the central monument are in the of socialist realist style of architecture that was being exported from the Soviet Union to what had become the People's Republic of Poland and was subjected to the Soviet sphere of policital, cultural and economic influence and abuse. The cemetery was inaugurated on 9 May 1950, the Victory Day, to mark the 5th anniversary of the capitulation of the Third Reich to the Soviet Union and the remaining Allies.

Ashes of the soldiers are buried in 834 graves, with 294 of them individual graves and the remaining 540 mass graves. The central part of the cemetery is a wide avenue that leads through three terraces to a 35 metre tall granite obelisk.

The necropolis was designed by architects Bohdan Lachert and Władysław Niemirski (who worked on the greenery) and its monumental sculptures were made by Jerzy Jarnuszkiewicz and Stanisław Lisowski.

The obelisk inscription used to read (in Polish with a parallel text in Russian):

"Ku wiecznej chwale bohaterskich żołnierzy niezwyciężonej Armii Radzieckiej, poległych w bojach z hitlerowskim najeźdźcą o wyzwolenie Polski i naszej stolicy Warszawy."
That is:
"To the eternal glory of heroic soldiers of the invincible Soviet Army, fallen in battles with the Hitlerite invader for the liberation of Poland and our capital Warsaw."

However, in 2015 this was changed to:

Polish
"Pamięci żołnierzy Armii Radzieckiej poległych o wyzwolenie Polski spod okupacji niemieckiej w latach 1944-1945."
with the parallel, though slightly different, Russian text:
"Вечная слава воинам советской армии, погибшим за освобождение Польши от немецко-фашистских захватчиков в 1944 . 1945 гг."

The Polish text means:
"To the memory of Soviet Army soldiers fallen in liberating Poland from German occupation in the years 1944-1945."

The cemetery dedication on the right side hold a Polsh language list of the units to which the dead belonged. The same dedication appears on the left, in Russian, along with another relief. The units were:

the 8th Guards Army
the 28th, 47th, 48th, 65th, 69th, 70th Armies
the 2nd Guards Tank Army
the 6th and 16th Air Army
the 46th Marksmen Corps
the 2nd and 7th Cavalry Corps
the 1st Guards Tank Army.

The cemetery is surrounded by artistically composed greenery designed by Władysław Niemirski and by a park.
