caption_attribution_description: English: J.C. Nichols Fountain by Henri-Léon Gréber (1910), at the Country Club Plaza, Kansas City, Missouri The fountain was created in Paris by sculptor Henri-Léon Gréber (1855-1941) in 1910 for the Clarence H. Mackay Estate called "Harbor Hill" in Roslyn, New York (landscape designed by his son Jacques Gréber); installed in Kansas City, Missouri in 1960. The allegorical statuary of the four large, cast bronze equestrian figures reportedly represent four great rivers of the world: the Rhine, the Seine, the Volga and the Mississippi.
context_page_description: Harbor Hill is the highest point in Nassau County, New York, at 348 feet. It was the site of Harbor Hill, a large Long Island mansion built from 1899–1902 in Roslyn, New York, commissioned by Clarence Hungerford Mackay. It was designed by McKim, Mead & White, with Stanford White supervising the project. It was the largest home he ever designed.
  Clarence Mackay was the son of Comstock Lode magnate John William Mackay, and inherited much of an estimated $500 million fortune upon his father's death in 1902. White collaborated closely with Clarence Mackay's wife, Katharine Duer Mackay, and with her approval, based the main façade of Harbor Hill upon that of François Mansart's Château de Maisons of 1642, using a mix of other influences to finish the overall design.
  Built at great expense and furnished lavishly, the home originally sat on 688 acres and enjoyed views across Roslyn Harbor to Long Island Sound. Formal terraces and gardens were finished by Guy Lowell.
  Social events held at the house included a grand party for the Prince of Wales in 1924.
context_section_description: Much of the estate, including the site of the main building, has been covered with a modern housing development. However, three remaining buildings from the Harbor Hill estate were listed on the National Register of Historic Places in 1991: Mackay Estate Dairyman's Cottage, Mackay Estate Gate Lodge, and Mackay Estate Water Tower.
