Gefängnis Rummelsburg, Former workhouse and prison in Lichtenberg, Berlin, Germany

Gefängnis Rummelsburg is a former workhouse and prison complex on Rummelsburger Bucht in Berlin-Lichtenberg. Between 1877 and 1879, city architect Hermann Blankenstein built six detention buildings, utility structures and a separate infirmary, all enclosed by a high brick wall. A detached building, Haus VIII, served as a punishment and detention house for male "Corrigenden". The surviving buildings now contain flats and a hotel.

Built between 1877 and 1879 by architect Hermann Blankenstein, it originally housed homeless people and those convicted of minor crimes. The facility was later converted into East Berlin's main prison and held thousands of inmates until German reunification in 1990.

The memorial and information site, inaugurated on 12 January 2015, was designed by graphic artist Helga Lieser with Peter Francis Lewis and landscape architect Jens Henningsen. Three metal steles in front of one of the main buildings on Hauptstraße stand 5 metres tall, matching the height of the largely demolished perimeter wall. Their surfaces mark the eras: rust for the imperial period, matte for the Nazi years, grey for the DDR. Eighteen further panels across the grounds give short biographies of former inmates.

The memorial and information point at the Hauptstraße was inaugurated on 12 January 2015; its three metal steles are 5 metres tall, matching the height of the former perimeter wall. Eighteen additional panels across the grounds give short biographies of former inmates. The site lies on the Rummelsburger Bucht in Lichtenberg; much of the former prison area is now housing, so visitors should keep to public paths.

Several areas still display graffiti and inscriptions left by prisoners during the East German period, offering direct evidence of life behind bars. These personal marks allow visitors to connect with the human dimension of the place in a tangible way.
