Overview

Centreville was a municipality in St. Clair County in the U.S. state of Illinois. Situated in the Metro‑East area across the Mississippi River from St. Louis, it formed part of the broader urban and suburban landscape commonly associated with the United States Midwest. The community functioned as a local center for housing and neighborhood services within the county.

Geography and character

Located in southwestern Illinois, Centreville occupied lowland and suburban tracts that linked smaller towns to the larger metropolitan core. Its proximity to regional transportation corridors and to the city of St. Louis shaped residential patterns and economic ties. The built environment included residential neighborhoods, small commercial corridors, and municipal facilities serving local residents.

History and municipal change

Centreville developed as part of the growth of the Metro‑East region in the 20th century. In recent years the community underwent a significant change when it joined with neighboring municipalities to form a single incorporated entity. That consolidation, completed in 2021, merged Centreville into the new city now known as Cahokia Heights, reflecting broader efforts to reorganize local government and coordinate services. For background on local governance see St. Clair County.

Government, services, and legacy

The consolidation aimed to streamline administration, reduce duplicative functions, and provide a unified approach to public services such as policing, public works and community planning. While Centreville no longer exists as an independent municipality, its neighborhoods, institutions and history remain part of the fabric of the new city and of the Metro‑East region.

Notable points

  • Part of St. Clair County and the Greater St. Louis metropolitan area.
  • Example of municipal consolidation intended to improve local governance.
  • Its identity persists within the successor city; historical references to Centreville remain in local records and community memory.
