McHenry County Historical Society

Organized in November 1963, as a not-for-profit corporation, the McHenry County Historical Society has as its mission to identify, preserve, present, and promote through education the history of McHenry County. Further, the Society's mission includes educational objectives aimed at encouraging a county preservation ethic. 

The Society's Museum in Union opened in 1976.  It's comprehensive collection includes several preserved buildings: an 1843 log cabin, 1867 one-room school, an 1885 Town Hall, a 20th Century modern tourist cabin, and an 1867 one-room school house used for school programs.  In 1982, a local history research library was added to the museum.

Besides operating the museum, the Society plaques historic sites and structures, holds adult workshops/classes, operates a traveling exhibit, and arranges school and group programs.
