Eighty Acres is a public art installation of 12 photographs, pasted onto the boarded up windows of the historic Union Block building in Mount Pleasant, Iowa. Each photograph is a fragment of a larger aerial photograph of rural Iowa, patched together to represent a disjointed whole when viewed at ground level.
The third story of the building originally housed the Opera House, a community gathering space in the late 1800's, vacant at installation except for a first floor restaurant and nail salon, and a few second floor apartments. In the winter of 2011, a fire destroyed the nail salon and apartments, condemning the entire building. 9 of the 12 plywood photograph windows survived the fire. In 2014 the entire building was renovated and restored.
