The Saint-Gaudens National Historical Park—the preserved home, studios, and gardens of sculptor Augustus Saint-Gaudens—is located in Cornish, New Hampshire, not Ossining, New York. The address is 139 Saint-Gaudens Road, Cornish, NH 03745.
Saint-Gaudens summered there from 1885 and made it his year-round home from 1900 until his death in 1907. The 190-acre property became a National Historic Site in 1964 and a National Historical Park in 2019. It displays over 100 of his works, including the iconic Standing Lincoln, the Adams Memorial, and the 1907 $20 "Double Eagle" gold coin design.
Ossining, NY, is about 200 miles south; there is no Saint-Gaudens memorial there.
