Washington County's Location

Washington County, Missouri was organized August 21, 1813 from Ste. Genevieve County. The County Seat is Potosi, Missouri, 63664.

Frenchmen RENAULT and LaMOTTE toured the area near present-day Potosi in 1722-23. No permanent settlement was made until 1763, when Francis BRETON settled near Potosi and began to operate a mine bearing his name. The Bellview Valley, near Caledonia, was settled in 1802 by Annanias McCOY, Benjamin CROW, and Robert REED.

Washington County is divided into eleven Townships:
