About Union

Located about sixty miles northwest of Chicago in rural McHenry County, Union is a quiet village surrounded by open fields and rolling farmland. With just a few hundred residents, it offers a peaceful, unhurried lifestyle where neighbors know each other and there is plenty of room to breathe. Everyday essentials, shopping, and dining are an easy drive away in nearby Woodstock and Huntley, making it a great retreat for anyone who values privacy and space.

The village is best known across the Midwest as the home of the Illinois Railway Museum, where visitors gather throughout the summer to ride beautifully restored steam locomotives and vintage streetcars. Main Street also features the McHenry County Historical Society Museum, adding to the area's rich heritage and classic small-town character. For homebuyers looking for countryside quiet with genuine local charm, Union is an inviting place to put down roots.
