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.
