Over the course of its history, Sunset Hills was known by many names before its incorporation in 1957. For many families, however, it has always been a constant; some Sunset Hills families are seventh-generation residents on land that was granted or purchased early in America's history. Early settlers were drawn to this community by the salt springs and clay mines. Indian tribes also utilized this area as an early regional site for trade and multi-tribal meetings along the Meramec River. The Meramec Landing Site was historically significant to both the tribes and the settlers, and the community formed eastward from this spot on the river, toward St. Louis. Today, the city encompasses over nine square miles. Largely considered a commuter suburb for St. Louis, Sunset Hills possesses its own rich history and strong sense of community.
