Washington County was created on October 27, 1849, in the Territory of Minnesota. (Minnesota was admitted to the United States as the 32nd state on May 11, 1858.) As one of Minnesota's original nine counties, Washington County is located on the eastern edge of the Twin Cities Metropolitan area and is composed of 423 square miles of land. The county seat is located in Stillwater, Minnesota, along the scenic St. Croix River.
Washington County has historically played a diverse role in the region, serving the Twin Cities with its commercial, industrial, natural, and agricultural resources. Today, Washington County is a place where a prosperous economy grows with vital industries. Population growth has caused a spread of highly developed urban areas in Woodbury, Cottage Grove, and Oakdale. The communities of Stillwater, Bayport, St. Paul Park, Newport, and Forest Lake have each developed economic bases that support a local labor force.
While much of Washington County has retained its rural atmosphere, today it is considered a suburban county. However, the county continues to maintain its diverse image--from the corn fields of Denmark Township to the residential neighborhoods of Woodbury; from the office and retail complexes along Interstate 94 to the cooling waters of the St. Croix River; from the lakeshore communities around White Bear Lake and Forest Lake to the pastoral wooded settings of the Scandia and May Township--each area of Washington County possesses a distinct set of landscapes and resources.
