About Plainville

Plainville got its start back in the 1820s as a quiet prairie settlement along the creek, and it still holds onto that peaceful, rural character today. Located in Adams County along Route 96, this small village offers a relaxed pace surrounded by western Illinois farmland. Local kids attend the school district in neighboring Payson just a few minutes up the road, giving residents an easy connection to nearby services while keeping day-to-day life quiet and unhurried. It remains a friendly, down-to-earth community where you can enjoy wide-open spaces and a genuine small-town feel.
