Union

A tight-knit village with approximately 500 residents, Union is committed to honoring its roots.  

Both the McHenry County Historical Society and the Illinois Railway Museum can be found in Union, allowing residents and visitors to step back in time. The historical society features a variety of exhibits that showcase the settlement and progression of various McHenry County towns, but perhaps even more impressive is the original schoolhouse that can be toured on site. Meanwhile, the railway museum features exhibits, model trains, and multiple barns filled with everything from restored Pullman cars to lumbering steam engines.  

Homes in Union vary from farmhouses to newer homes in subdivisions closer to a small downtown area. The village is considered Marengo's twin city, and the two communities share the same local government.  

When it comes to recreation, residents enjoy the 3.2-mile Huntley-Union-Marengo Trail, which welcomes activities like biking and running throughout the year.
