Smallwood State Park

Smallwood State Park takes its name from General View of the Smallwood HouseWilliam Smallwood, a native born Charles Countian. He was the highest ranked Marylander who served in the American Revolutionary War. His house, called Smallwood's Retreat, has been restored and is open to visitors seasonally. Besides the restored house, the 628 acre park offers a marina, boat launching ramps, a picnic area, camping area, pavilions, a recycled tire playground and nature trails. On occasion, there are craft demonstrations, military exhibitions and other special events.


Smallwood State Park was dedicated in September 1958, as a historic park. At the time, the park consisted of 30 acres of land which included the Retreat House and the grave site of General William Smallwood. Smallwood reached the rank of major general for his service as a patriot leader during the Revolutionary War. He was elected Governor of Maryland in 1785, and later served in the Maryland Senate. During his term as the 4th Governor of Maryland, Maryland ratified the Federal Constitution. The plantation house reflects Smallwood's lifestyle as a gentleman planter.

Sweden Point Marina was not always known as Sweden Point. At one time it was referred to as Sweetman's Landing. The area that is referred to as Grinder's Wharf (which is only a few exposed pilings today) was built on a naturally deep water channel in the Mattawoman Creek. The Grinder family was one of the areas major brick manufacturers in the Chicamuxen area. They in turn used Grinders Wharf to ship their brick out to the wholesalers. In the mid 1800's the wharf was used by the Washington Steamship Lines on the Potomac. The steamers would pick up water on their journey south to the Chesapeake Bay. A park map is available from the park office.
