The Karl Marx Monument (German: Karl-Marx-Monument) is a 7.10-metre-tall (23-foot-4-inch) stylized head of Karl Marx in Chemnitz, Germany. The heavy-duty sculpture, together with the base platform, stand over 13 m (43 ft) tall and weighs 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. It is the most famous monument in the inner city of Chemnitz, where it has gained the nickname "Nischel", which is derived from the Saxon term for head or skull.
