In September 2019, the National Oceanic and Atmospheric Administration (NOAA), the State of Maryland and Charles County announced the designation of Mallows Bay as the 14th national marine sanctuary in the nation. The purpose of the designation is to protect the remains of more than 100 abandoned steamships and vessels built as part of America’s engagement in World War I. This can't miss destination is located along an 18-square mile stretch of Potomac River coast in Charles County, Maryland, just 40 miles outside of Washington, D.C.  The new sanctuary boasts a collection of historic shipwrecks dating back to the Civil War, as well as archaeological artifacts nearly 12,000 years old. Its culturally rich landscape also includes sites that represent the history of Native American communities in the area, the once-booming Potomac River fishing industry, and the Civil War.
