The Hayden Flour Mill, located at the base of A Mountain, on Mill Avenue and near Tempe Town Lake, is one of Tempe’s most iconic buildings. History
The Hayden Flour Mill, as it stands, is the oldest cast-in-place, reinforced concrete building in Tempe. The mill that currently exists, however, is the third building erected on that site. The original mill started operations in 1874. The Hayden Flour
Mill was the larger of two such mills in the state until April 01, 1998, when Bay State Milling stopped operation ending the longest run of continuous use for an industrial building in the Valley.
