Gillespie, Illinois: Coal Country, Labor History, and the Original Route 66
Welcome to Gillespie, Illinois
Gillespie is a small city in Macoupin County with a Route 66 story rooted in coal, labor, and community resilience. Situated on the first alignment of Route 66 — the original 1926-1930 roadway — Gillespie was for much of the early 20th century one of the most industrially significant communities in southwestern Illinois, home to some of the largest coal mines in the world. Today, the Illinois Coal Museum on Historic Route 66 anchors a revitalizing downtown, and Gillespie’s legacy as a birthplace of the American labor movement gives it a depth of character that rewards travelers who take the time to learn its story.
Where Is Gillespie, Illinois?
Gillespie is located in Macoupin County in southwestern Illinois, approximately 45 minutes south of Springfield and about 45 minutes north of Staunton. The city sits on the original 1926-1930 alignment of Route 66, which runs through downtown along Macoupin Street. This first alignment — shorter-lived than later routes — is one of the most historically significant stretches of the Illinois Mother Road and passes through a remarkable concentration of former coal-mining communities.
The History of Gillespie
European immigrants poured into Gillespie in the 1880s drawn by the opportunity to work in the coal mines. The Superior Coal Company was by far the dominant industrial force in the city, and at its height Gillespie grew from a village of 600 residents to a boom town of more than 6,000 people. The coal industry brought prosperity but also hardship, and Gillespie became an important center of labor organizing in the early 20th century.
In 1932, dissatisfied with how negotiations were handled by the United Mine Workers of America, 274 miners’ delegates met in Gillespie’s Colonial Theater and formally broke away to found the Progressive Miners of America union. By 1933, the new union had more than ten thousand members, and Gillespie had become a significant player in the American labor movement. A historical marker on the site of the Colonial Theater — now a community garden — commemorates this founding moment.
When the original Route 66 was aligned through Gillespie in 1926, it added a new dimension to the city’s character as a traveler’s waypoint between Springfield and St. Louis. The coal mines gradually declined through the mid-20th century, leaving behind a smaller but proud community that continues to celebrate its heritage.
Route 66 Through Gillespie
The original 1926-1930 Route 66 alignment runs through Gillespie along Macoupin Street, the city’s main commercial thoroughfare. Heritage signage and Route 66 monuments mark the alignment, and the Illinois Coal Museum’s Route 66 Blue Carpet Corridor exhibit connects the highway’s history to the city’s mining past. The downtown streetscape along this alignment retains the character of a small-town commercial district from the early highway era.
What to See and Do in Gillespie
Illinois Coal Museum
The Illinois Coal Museum at 121 South Macoupin Street is the anchor of Gillespie’s Route 66 identity and the city’s most significant visitor attraction. The museum covers the history of Gillespie and the broader Illinois coal mining industry through exhibits on mining technology and equipment, the evolution of mining processes, labor union history, and the many mining disasters that shaped the region. The museum also features Route 66 information and memorabilia as part of its comprehensive Route 66 Blue Carpet Corridor exhibit. It is an ongoing, evolving institution with new exhibits added regularly, including a dedicated section on the story of the famous Coliseum Ballroom — a major Gillespie entertainment venue that hosted big names in the swing and early rock eras.
Progressive Miners of America Historical Site
The site of the Colonial Theater, where the Progressive Miners of America was founded in 1932, is now a community garden called the Colonial Giving Garden. A historical marker on the site — erected in partnership with the Illinois State Historical Society — commemorates the founding of the union and its significance to the American labor movement. For travelers interested in labor history, this is one of the most important and overlooked stops on the Illinois Route 66 corridor.
Canna Theater
The Canna Theater, a single-screen movie theater dating back to 1921, is one of the few surviving examples of early 20th-century small-town entertainment in the region. The theater continues to operate and is a charming piece of Gillespie’s downtown character.

Gillespie celebrates its coal mining heritage each June with Black Diamond Days, a community festival featuring a carnival, parades, contests, and mine rescue demonstrations. The festival is a vibrant expression of community pride and a genuine celebration of the industrial history that shaped the city.

Final Thoughts on Gillespie, Illinois
