Description
Mallows Bay-Potomac River National Marine Sanctuary is located along an 18-square mile stretch of Potomac River coast in Charles County. The sanctuary protects and interprets the remnants of more than 100 abandoned wooden vessels, steamships that were part of the naval effort in World War I—known collectively as the “Ghost Fleet”.
Beyond the Ghost Fleet, the area’s culturally rich landscape includes connections to the Revolutionary and Civil wars, as well as the rich heritage of commercial fishing operations, and three Piscataway tribal groups whose ancestors inhabited the Potomac shore more than 10,000 years ago. The sanctuary also has a collection of archaeological artifacts nearly 12,000 years old.
Trail signs interpret the area’s history and ecology.
The site’s importance is recognized by the National Register of Historic Places and its listing as a National Treasure by the National Trust for Historic Preservation.
