Cabarrus County – Cabarrus County was formed on December 29, 1792 and is located in the Piedmont area which is located in the south-central part of North Carolina. The county seat is Concord which was incorporated in 1803. Among its significant historic sites is the Reed Gold Mine, a National Historic Landmark. The first gold discovered in the United States was found here in 1799, resulting in a gold rush in the early 1800s. So much gold was mined that President Andrew Jackson established the US Mint to control it. This was an area of cotton cultivation in the antebellum era and industrialization through cotton mills in the late 19th century. The Charlotte Motor Speedway, a NASCAR Research and Development Office (which also is the headquarters for research for touring and sportscar racing operations), and several professional race teams are headquartered here.
