Prenzlauer Berg
Knaackstraße, the Ernst Knaack Youth Centre – later known as the "Knaack Klub" (Greifswalder Straße 224 in Prenzlauer Berg, Berlin) – and the Ernst Knaack Fourth Polytechnic Secondary School (Kastanienallee in Prenzlauer Berg) are named after Ernst Knaack. The stele "Traditionen der deutschen Arbeiterklasse" ("Traditions of the German Working Class") by Heinz Worner (Knaackstraße 53-67 in Prenzlauer Berg) is dedicated to the murdered antifascists Ernst Knaack and Siegmund Sredzki.
