Hayden Flour Mill is a relic of our agricultural past, when Tempe was a small town surrounded by miles of farmland and anchored, economically, by the processing and marketing of grain, cotton, fruit, vegetable, and dairy products.

The Hayden Flour Mill is the oldest cast-in-place reinforced concrete building in Tempe. The mill that currently exists is the third building erected on that site; the two previous mills burned. The original mill started operations in 1874.

The ground of the Hayden Flour Mill, is now open for picnics and casual recreation. A small grove of trees allows for shady picnics. The north lawn is also open as a special event venue.  The new Flour Mill site includes the opportunity for people to look through the ground floor windows of the Mill and see some of the equipment that was used to grind flour.
