The Old Mill Museum is located along the banks of the River Raisin. It contains three stories of permanent and changing exhibits. Downstairs at the museum includes antique tables and chairs that are used for events and meetings. Large graphic photos depicting the history of the Old Mill hang throughout the first floor.
Hand-crafted display cases tucked into reproduction storefronts contain changing seasonal exhibits. Exhibits of second and third floor include some of the original Village of Dundee Council tables. The bell from the now-demolished Rea Church hangs in the Museum and can be rung by visitors. The museum is open from 12-4 every Friday, Saturday, Sunday and Monday.
