County Welcome

Welcome to St. Clair County and to the City of Belleville, our county seat! Both St. Clair County and the City of Belleville have a rich history. St. Clair County was Illinois’ first county having been created in 1790. The City of Belleville was formed in 1814. The City of Belleville (200 years) and the County (225 years) both have recently celebrated milestone anniversaries.

Belleville has a rich cultural background, quality schools, growing businesses and a great quality of life. It is a great place to live, work and play. The County is home to Scott Air Force Base, MidAmerica St. Louis Airport and St. Louis Downtown Airport. We have a successful light rail system, MetroLink, connecting Belleville and other communities in the county with the Missouri portion of the region. We are home to Southwestern Illinois College, McKendree University and Lindenwood University’s fast growing Belleville Campus as well as other institutions of higher learning with satellite locations at Scott Air Force Base and in Belleville. We offer many great attractions, historic neighborhoods, tourist destinations and year round activities for the entire family.

I welcome you to contact my office if you want to learn more about our vibrant and growing region.
