Island and U.S. national memorial in Washington, D.C.
Theodore Roosevelt Island is an 88.5-acre (358,000 m2) island and national memorial located in the Potomac River in Washington, D.C. During the Civil War, it was used as a training camp for the United States Colored Troops. 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.
In the 1930s, landscape architects transformed Mason’s Island from neglected, overgrown farmland into Theodore Roosevelt Island, a memorial to America’s 26th president. They conceived a “real forest” designed to mimic the natural forest that once covered the island. Today miles of trails through wooded uplands and swampy bottomlands honor the legacy of a great outdoorsman and conservationist.





The park is open every day from 6:00 AM to 10:00 PM.
