Where Modern Sustainability and History Connect.

Ahead of its time then and still today. Constructed in 1930 for a quarter-million dollars, the Firestone Tire Plant was deemed “one of the most modern tire structures in the West” at the time of opening. Equipped with “thousands of dollars of ‘almost human’ mechanical equipment” boasting a “one-stop shot” for automotive service, a new idea for the era.
