Caseyville may be one of Illinois' smaller villages, but its address in St. Clair County puts renters within easy reach of a major American city and a site of global historical significance. The village traces its roots to 1849, when the Illinois Coal Company founded the town and named it for Zadok Casey, a former U.S. Representative and Lieutenant Governor of Illinois. That coal-mining heritage shaped the tight-knit, grounded character the community still carries today.
Just a short drive away, Cahokia Mounds State Historic Site stands as the largest pre-Columbian settlement north of Mexico and a UNESCO World Heritage Site, a remarkable neighbor for such a quiet suburban address. Downtown St. Louis is roughly 20 minutes by car via Interstates 255 and 64, and the nearby Fairview Heights MetroLink station offers a rail connection into the city for those who prefer to leave the car behind. Scott Air Force Base sits about 32 minutes away, anchoring a strong military presence across the metro-east region. Saint Louis University and Southwestern Illinois College are both accessible within about 23 minutes.
The rental market here leans toward modest single-family homes and smaller apartment communities, with rents that run well below the Illinois state average, making Caseyville a practical option for those who want metro St. Louis access without the price tag.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
