Untermyer Park and Gardens in Yonkers preserves part of the former Greystone estate on a steep Hudson River site north of New York City. Created in 1865, the property passed from John T. Waring to Samuel J. Tilden and then to Samuel Untermyer, who expanded it and, beginning in 1916 with William Welles Bosworth, transformed it into an elaborate garden complex. Its most celebrated feature is the 3-acre Walled Garden, an Indo-Persian-inspired design adapted to rocky terrain with canals, fountains, classical structures, and sculpture. After opening widely to the public in the 1920s and 1930s, the estate declined, but restoration since 2011 has revived this unusual formal garden.
