About St. Marys

Located in Warren County just south of Des Moines, St. Marys is a quiet, tight-knit town with deep roots. Founded in 1870 around the Immaculate Conception Church by German and Irish settlers, the community has held onto its small-town charm through generations. While the local school closed years ago, neighbors preserved its historic bell and sign in the town’s memorial park. Today, residents enjoy the peaceful pace of rural living while staying just minutes from shopping, dining, and work opportunities in nearby Indianola and the metro area.
