Tudor Hall is an important 18th century house in St. Mary's County, Maryland. An example of Georgian architecture, it is the oldest building in Leonardtown. Tudor Hall was built by the Barnes family, either Abraham or his son, Richard, both of whom were active in the American Revolution. The name Tudor Hall was given to the house by a 19th century owner, Henry G.S. Key, a cousin of Francis Scott Key.

St. Mary's County has been making history since the Ark and Dove arrived here from England in March 1634. Maryland was the 4th successful English colony in what was to become the United States and St. Mary's is known as the Mother County of Maryland. Established in 1951, the St. Mary's County Historical Society strives to identify, collect, and preserve materials of any kind related to the history of this area. Find and follow your roots and history back to 1634.
