The trenches of World War I design salutes the American men and women who fought a horrific war by invoking the environment in which it was waged - years after the Armisitice. As the visitor draws near, a sign saying World War I Memorial leads to a ramp and a below ground trench that unwinds across Pershing Square, Park. In illuminated words and pictures, the walls of the trench tell the story of World War I.
