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 State Park takes its name from General William Smallwood, a native born Charles Countian. He was the highest ranked Marylander who served in the American Revolutionary War. To us, it was a pretty nice walk (to sober up a little bit ...) !!
