About St. Augustine

Located in southwestern Knox County right near the Fulton County line, St. Augustine is a quiet rural village with deep local roots. The community was first settled in the 1830s about a half-mile south of its current spot, but shifted north in the 1850s to connect with the new railroad line. Locals still call that original settlement area Old Town, and the village today offers a peaceful, slow-paced setting surrounded by western Illinois farmland.
