Duse died of pneumonia at the age of 65 in Pittsburgh in Suite 524 of the Hotel Schenley while on the eastward return leg of a tour of the United States. (The Hotel Schenley is now the William Pitt Union at the University of Pittsburgh.) A bronze plaque in the lobby commemorates her death. After being moved to New York City, where she lay in state for four days before her funeral service, her body was returned to Italy (where another service was performed). She is buried in Asolo – where she had made her home for the last four years of her life – at the cemetery of Sant' Anna. Her daughter Enrichetta donated some of her mother's items to the state in 1933. These items are preserved in Asolo in the Museo Civico. In 1968 her granddaughter Eleonora Ilaria Bullough (aka Mary of St. Mark as a Dominican nun) donated the last items to the Giorgio Cini Foundation in Venice.
