Day’s End is a permanent public art installation in the Hudson River Park. It was proposed by New York City artist David Hammons in collaboration with the Whitney Museum of American Art. The structure is conceived as a "ghost monument" to the celebrated work of the same name by artist Gordon Matta-Clark, who cut giant openings into the since demolished Pier 52 building. Hammons’ work—a minimal, ethereal frame—outlines a place that no longer exists. It raises important questions about the waterfront, inviting viewers to consider the social, cultural, economic and environmental history that it invokes.
