Situated in the heart of Spencerville, the Spencerville Mill & Museum stands as a testament to the town's rich history, offering a window into rural life during the 1930s when the population hovered around 250. With over 160 years of history, this iconic structure served as a crucial community hub until its closure in 1972, showcasing architectural resilience with 20-foot-high ceilings, old wooden beams, and meticulously restored stone walls.

Undergoing restoration through collaborative efforts, the mill is now a guardian of the past, emphasizing the 1934 feed mill operation and local businesses of that era. Visitors can marvel at the 1934 Charles Barber 110 HP water turbine, restored in 2007, as it springs to life with a mechanical symphony. The Spencerville Mill & Museum Park, nestled along the riverbank, offers a serene escape for relaxation, wildlife observation, and picnics. Open daily with guided tours in July and August, the museum hosts events and programs from May to October, inviting all to explore the last remaining mill on the South Nation River, tracing its evolution into a vital feed mill.
