The Frederick Armbruster Cottage is a historic residence located in the Eliot neighborhood of Portland, Oregon, United States. Built in 1898, it is a locally-important example of the application of the Queen Anne style to simple housing for the European immigrant and working class families that flowed into the neighborhood during the 1880s to early 1900s. The German American Armbruster family operated a pretzel baking business from the back yard for nearly 30 years.[2]
