St. Clair County Courthouse

The St. Clair County Courthouse sits at Public Square in Belleville and serves as the central place for criminal and civil cases in the region. It houses multiple courtrooms and offices where legal matters from across the county are processed and heard.

The courthouse was established in the 1800s and has remained central to the judicial system of the county ever since. The building has evolved from its original structure to accommodate modern legal proceedings while maintaining its role in regional justice.

The building embodies the legal heritage of the region and demonstrates how the courts have evolved over time. Visitors walking through the halls can sense the weight of decisions made here and understand how justice operates in this community.

The building is open to visitors during weekday hours, and information desks can help direct you to specific courtrooms and proceedings. Be aware that certain areas are restricted and security screening is required before entering.

The courthouse handles cases from about thirty different municipalities across the entire county, making it a central hub for legal proceedings in a wide area. This regional role means it manages justice matters that extend far beyond the city of Belleville itself.
