Marshall County, created in 1839 and named for Chief Justice John Marshall, lies along the Illinois River in north-central Illinois. Its county seat is Lacon, and other towns include Henry, Toluca, Wenona, and Sparland. The area is scenic, with rolling farmlands, wooded bluffs, and riverfront views. Agriculture remains the dominant industry, but the river also supports recreation and small-scale manufacturing. The housing market is affordable and rural — existing homes typically range $150,000–$220,000, with larger or updated properties around $280K+. New construction (land + build) averages $250K–$350K, depending on size and site location. Marshall County is quiet, family-oriented, and ideal for those seeking space and small-town friendliness. Its proximity to Peoria (about 30 miles south) allows access to urban conveniences while maintaining a relaxed country lifestyle. Lacon’s riverfront charm and Henry’s rural community spirit make this one of Illinois’ underrated, peaceful counties.
