The Poelzig-Block 6 is part of the Poelzig-Bauten. It was built in 1928 and 1929 after the plans by Hans Poelzig. Arnold Kuthe's construction business was responsible for the construction. The client was Alfred Schrobsdorff KG.
The property was the reason why the district border from Prenzlauer Berg was moved a few meters forward on June 19, 1929, as otherwise it would have been in two districts.
In 1931 Dr. Rudolf Wiehler lived here. 
Today it houses the Bar 3 and the Merlin Apotheke.
