A grand Hudson River Estate with a Gothic Revival mansion, designed by Alexander Jackson Davis in 1838. It is the type of place Jackson's friend, and America's pioneer landscape architect, Andrew Jackson Downing, wrote about in his chapter on 'Landscape or rural architecture' (in his Treatise on the theory and practice of landscape gardening, adapted to North America,1841). Behind Davis and Downing looms the presence of John Claudius Loudon, author of Encyclopedias on Gardening and Architecture. Lyndhurst was bought by a railway magnate Jay Gould in 1880. The garden has sweeping lawns, shrubs, specimen trees, a curving entrance drive, steel-framed conservatory, fernery and a circular rose garden with central gazebo.
