About Andalusia

Andalusia is a Mississippi River village in Rock Island County, with the waterway shaping its western edge and its connection to the Quad Cities region. Before U.S. settlement, this stretch of river was home to Sauk and Meskwaki people; after the Black Hawk War, American settlement took hold along the river. Today the village reaches back from the waterfront into wooded and hillside ground, keeping the river and the county road network in the same local picture.

Local routines run through Rockridge Community Unit School District 300 and a volunteer-based emergency-service network. Andalusia's ambulance service and fire department work with surrounding communities, while the Rock Island County Sheriff's Office operates the local substation. That arrangement gives the village a regional service pattern: schools, emergency response, and law enforcement cross village lines even as Andalusia keeps its own offices and riverfront identity. Andalusia is small in scale, yet its daily connections run along the Mississippi and across county lines for school and emergency services.
