The following properties of historical significance are in danger of being destroyed.
The Dubuque Brewing and Malting Company - 30th and Jackson

​​​​Built in the 1890's, when local breweries consolidated to form one of the largest breweries in the Midwest.  It closed during the Prohibition, and attempts to reopen as a brewery after failed. It later became a packing plant.  It was a storage facility for the Dubuque Pack and the H&W Motor Express.  The City Council created a special district to prevent teardown. The North and South portions now have separate owners, who operate businesses out of each half. It is an example of Romanesque Architecture.
