Macoupin County, formed in 1829 and named after the Macoupin plant (wild potato) once common in the area, is located in southwestern Illinois. The county seat is Carlinville, known for its grand historic square and “Million Dollar Courthouse.” Other communities include Gillespie, Staunton, and Virden. The region’s landscape is largely agricultural, dotted with forests and small lakes. Housing is affordable, with typical existing homes priced between $150,000 – $230,000, while renovated farmhouses or lake-view properties may reach $300K+. Building a home (including land) generally costs $250K – $350K. The county’s proximity to St. Louis (roughly 60 miles south) makes it attractive for those seeking a rural home within commuting distance to a major city. Life here is quiet, family-friendly, and steeped in historic character — Carlinville itself feels like a preserved piece of small-town Americana.
