Lyndhurst is a notable Gothic Revival country house within its own 67-acre park beside the Hudson River, located in Tarrytown, New York approximately one-half mile south of the Tappan Zee Bridge on US Route 9. The house was designed in 1838 by Alexander Jackson Davis, and has been the home of former New York City mayor William Paulding, merchant George Merritt, and railroad tycoon Jay Gould, whose daughter Anna, Duchess of Talleyrand-Perigord, donated it to the National Trust for Historic Preservation in 1961. It is now open to the public.
