Theodore Roosevelt Island

Theodore Roosevelt Island is an 88.5-acre island and national memorial located in the Potomac River in Washington, D.C. The island was given to the federal government by the Theodore Roosevelt Association in memory of the 26th president, Theodore Roosevelt. Until then, the island had been known as My Lord's Island, Barbadoes Island, Mason's Island, Analostan Island, and Anacostine Island.
The island is maintained by the National Park Service, as part of the nearby George Washington Memorial Parkway. The land is generally maintained as a natural park, with various trails and a memorial plaza featuring a statue of Roosevelt. No cars or bicycles are permitted on the island, which is reached by a footbridge from Arlington, Virginia, on the western bank of the Potomac.
