I’ve been to this island before but don’t recall ever seeing this memorial.

Theodore Roosevelt Island is an 88.5-acre (358,000 m2) island and national memorial located in the Potomac River in Washington, D.C. The island is maintained by the National Park Service as part of the nearby George Washington Memorial Parkway and 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.
