Belleville earns its French name, "belle ville," or beautiful city, with a downtown of brick-paved sidewalks, locally owned shops, and a lively arts scene, all about 15 miles southeast of Downtown St. Louis. Neighborhoods closest to the historic town square put daily errands within easy walking distance, while areas farther out offer a more spacious, suburban feel. The city is the most populated in the Metro East region and serves as the county seat of St. Clair County, with Scott Air Force Base about 12 miles away adding a steady presence of military and federal civilian personnel.
Renters can choose from ranch-style homes, brick colonials, Craftsman bungalows, and garden-style apartment communities spread across 24 square miles. That architectural range spans the 19th and 20th centuries, giving the city real depth and character that newer suburbs often lack. Southwestern Illinois College has a campus here, adding an academic energy to the community. The National Shrine of Our Lady of the Snows draws visitors year-round, and Art on the Square ranks among the top fine arts shows in the country.

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.
