The Karl Marx Monument (German: Karl-Marx-Monument) is a 7.10m (23.29ft)-tall stylized head of Karl Marx in Chemnitz, Germany. The heavy-duty sculpture, together with the base platform, stand over 13 meters (42 feet) tall and weights approximately 40 tonnes. On a wall just behind the monument, the phrase "Workers of the world, unite!" (from the Communist Manifesto) is inscripted in four languages: German, English, French and Russian.
