Wisconsin's building, by R. A. Messmer & Brother of Milwaukee, was a two-story classical mansion in "travertine", about 46 by 133 feet. The state arms were over a broad paired-column portico on the south, and there were more porticos to east and west. The Official Guide calls it Colonial. Inside were a hall with an open fire, rest rooms, the Commission's offices, and the ruins of a clock made by John Muir.
Wisconsin Day was August 9, 1915. After the fair the building was one of several barged across the bay to Santa Venetia in Marin County (Todd names Virginia's Mount Vernon as another). Their later fate is not recorded in the sources consulted.
