The Metropolitan Museum of Art’s popular Roof Garden Commission series has seen a bamboo forest and a maze of steel and mirrored glass constructed on top of the institution’s Beaux-Arts building. For this year’s installation, which opens on Tuesday, April 19, British artist Cornelia Parker has created a replica of the Bates house from Alfred Hitchcock’s 1960 film Psycho. Parker used materials from an abandoned, early-twentieth century barn in upstate New York to build the twenty-eight-foot-high structure.
