St. Mary’s County

For nearly four centuries, St. Mary’s County has been called the land of pleasant living. The county’s fertile fields and pristine waters invite visitors and natives alike to revel, relax, and renew. As the Mother County of Maryland, St. Mary’s has a rich written history dating from 1634, when George and Leonard Calvert established the first American settlement founded on the principle of religious tolerance. After surviving British raids during the War of 1812 and divided loyalties in the Civil War, the county leapt into the modern era when the US Navy established Naval Air Station Patuxent River, the Navy’s premier flight test center and test pilot school. Today, millions of Americans trace their roots to Southern Maryland and are welcomed home as Sons and Daughters of Old St. Mary’s.
