Mason County, established in 1841 and named after George Mason, sits in the heart of central Illinois along the Illinois River. The county seat is Havana, a town with a scenic downtown, antique shops, and beautiful river views. The county is heavily agricultural but has rich wetlands and outdoor recreation areas — including wildlife refuges and hunting grounds that attract visitors. The housing market is modest, with median prices ranging $130,000–$190,000, though river-view or newer homes may reach $250K+. Building new homes (including land and infrastructure) typically runs $220K–$320K. The area is primarily rural, with small communities like Manito and Forest City providing basic services. Havana offers schools, dining, and community events. The county’s character blends outdoor adventure and simplicity — ideal for retirees, hunters, or those seeking affordability in a quiet, natural setting.
