History of Washington County

Long ago, in 1722 and 1723, French explorers named Renault and La Motte visited the area where Potosi is today. But they didn't build any lasting homes there.

The first permanent homes were made in 1763. A person named François Breton settled near Potosi. He started a mine there that was named after him. Later, in 1802, more families settled in Bellview Valley. This area is near Caledonia and Belgrade. Washington County was officially formed from Ste. Genevieve County on August 21, 1813.
