Congress (aka Old Congress) is a census-designated place (CDP) in Yavapai County, Arizona, United States. Once a gold-mining center for the Congress Mine and then a ghost town, Congress now serves as a retirement and bedroom community for nearby Wickenburg. The population was 1,811 at the 2020 census.
History
Gold was discovered at the Congress Mine in 1884. By 1893, the Santa Fe, Prescott and Phoenix Railway passed within three miles of the mine, at Congress Junction. Congress boomed, and remained prosperous until the mid-1930s, when the mines closed. Total gold production at the Congress Mine exceeded $8 million, at the then-current price of $20.67 per ounce – or about $400 million, at the 2007 price.
The post office moved to Congress Junction in 1938, where it remains. The community now known as Congress is the old Congress Junction. Little remains at the original mining-camp townsite. The old Congress Cemetery is nearby.
