The title fireworks show of James Whistler's Nocturne in\n Black and Gold takes place over one of these objects. One of these objects named "Maidenhead" is thought\n to have inspired the one J.M.W. Turner painted in Rain, Steam and Speed. A Japanese inspired structure of\n this type at Giverny was often painted alongside water lilies by Claude Monet.
