The Adams County Historical Society (ACHS) was organized in 1972 and received its non-profit 501(C)3 classification in 1974.

 

The Adams County Museum opened in 1987, occupying the former golf clubhouse located at the Adams County Fairgrounds. 
 

Over the years, the museum grew beyond a single building into the complex it is today – housing the History Museum & Office, Cultural Center, a replica one-room Schoolhouse, a replica 1930s Conoco Station, a working Blacksmith Shop, a Firehouse, a restored 1887 two-story Victorian House, a 1920 Railroad Caboose and the 120-foot by 60-foot  Hoffman Hall, which is full of several exhibits, including an actual jail cell from the old Adams County Jail, a printing press, Western gear and tack (including a saddle used by a Pony Express rider), vintage housewares, antique tools and medical equipment and a military section that holds uniforms, flags, radios and swords.


The property also features a Japanese Garden, Sundial, several sculptures, Windmill, Gazebo and a Howe Farm Scale.


ACHS is governed by a Board of Directors. They are just a few of the many dedicated volunteers who help keep this nonprofit operating.

 

Our funding mainly comes from the Scientific & Cultural Facilities District (SCFD) and our annual fundraisers, which would not be possible without volunteers!
