McHenry County Historical Society

Educating and Preserving History since 1963.

Since the mid-1960s, the McHenry County Historical Society has provided the methods and means of presenting McHenry County History to enrich life. Please join us in celebrating over 50 years!

Besides operating the museum, the Society plaques historic sites and structures, holds adult workshops and classes, makes available traveling exhibits and arranges a wide variety of school and other group programs.

Funding for the Society comes from membership dues, admission fees, donations and a trust fund. For many years, we have published a comprehensive quarterly newsletter, The Tracer. To receive this valuable resource, join our organization.  For more information visit The Museum. We very much appreciate your interest and invite you to participate.

Museum is Open May - October in Union IL.

On July 4, 1976, the Society's museum in Union, Ill. officially opened to the public. The Museum is open May through October, 1 to 4 p.m. Tuesday through Friday, and most Saturdays from 11 a.m. to 4 p.m. The museum is closed for major holidays. Please call or check our calendar if you are unsure. Admission charge for nonmembers. Adults - $5, Seniors (60+) and Students - $3, and Family (Includes 2 family member adults and 2 or more children) - $12. The museum is occasionally open during special programs in the evenings or weekends.

Our comprehensive collection includes several preserved buildings: The 1843 Gannon Log Cabin, an 1885 town hall, now known as Perkins Hall; a 20th century modern tourist cabin, restored and housed inside the Museum. In 1982, a local history research library was added to the museum. In 1988, we acquired the West Harmony School, an 1895 one-room schoolhouse now used for circa.1900 school programs at our Museum location in Union. In 2009, we acquired the 1898 Riley Methodist Church.

The McHenry County Historical Society also collects local history. Our Research Library has as its purpose the acquisition, cataloguing and preservation of documentary materials that relate to the history of McHenry County and its people. When consistent with the mission of the Society, these materials may be made available to the public for research, study and promotional purposes.

The library hours are Monday through Friday, 9 a.m. to 4:30 p.m. year round. There is a fee for use by non-members.The Research Library is accessible by appointment only. Walk-ins cannot be accommodated no matter what the circumstances or the distance traveled since supervision is required. Materials must be retrieved by staff for security and archival reasons. Also, please understand that we are a nonprofit organization with a small staff trying to do many things, often simultaneously. Call our office at 815-923-2267 to make your library appointment.
