Colonel Boyce Thompson’s home above the arboretum. This photo was taken shortly after the completion of the main house in 1924. Known as the Picket Post Mansion or "Castle on the Rocks," it was Colonel Thompson's winter retreat until his death in 1930. Thompson donated the house and land to the Arboretum in 1928. | Date: 1925 | Source: Boyce Thompson, "The Unexciting Truth About William Boyce Thompson’s Picket Post Mansion," Thompson Family History, n.d. accessed May 16, 2024 <https://thompsongenealogy.com/2023/04/will-picket-post-remodel-capture-the-spirit-of-its-creator/>. | Rights: Thompson Family HistoryDownload Original File
