The Socialists' Memorial, Memorial site in Lichtenberg, Germany

The Socialists' Memorial is a burial and memorial site within the Friedrichsfelde Central Cemetery in Berlin. At its centre stands a tall, upright block of pale tan and grey porphyry with a rough surface, engraved with the words "DIE TOTEN MAHNEN UNS". Around it, on a circular bed of dark soil edged by a low stone border, lie twelve flat stone markers with bronze plaques, arranged in a ring.

The 1926 memorial by Mies van der Rohe, a wall of protruding and recessed hard-fired bricks built by Bauhütte Berlin workers, was unveiled on 13 June 1926 and inaugurated on 11 July 1926. From 1933 the Nazis tore down its five-pointed star and flagpole, and in early 1935 had the structure removed down to its foundation and the graves levelled. After the war the monument was not rebuilt; in 1946 it was provisionally reproduced, and the present Gedenkstätte der Sozialisten was inaugurated on 14 January 1951.

The site's name comes from its role as the burial ground of the workers' movement: Wilhelm Liebknecht's 1900 funeral drew a procession of around 150,000 people, and the cemetery soon became known as the Sozialistenfriedhof. Since 1990 no new graves have been allocated here, though urns of relatives of those buried before 1989 can still be placed in the adjoining Pergolenweg plot.

The memorial lies inside the Zentralfriedhof Friedrichsfelde, reached from the main entrance; the circular bed with the central stele and the four flat markers with bronze plaques sits on level ground. The site is a burial ground, so visitors keep to the paths and stay quiet near graves. The adjacent Pergolenweg grave area continues the same route.

The memorial's central stele is made of long-grain porphyry, and beside it stand twelve stone slabs engraved with the names of labour-movement leaders, among them Karl Liebknecht, Rosa Luxemburg, Ernst Thälmann, Rudolf Breitscheid and Franz Mehring. The site was inaugurated on 14 January 1951 in the presence of Wilhelm Pieck, Friedrich Ebert junior and Erich Honecker.
