Thacher Street became Windermere Road about 1904. The street was constructed through the middle of the old Thacher estate.
The old Thacher estate was called Hillside and occupied the land on Jones Hill stretching from about where Cushing Avenue is now at the top of the hill down to Stoughton Street. The house later served as the Harley Hospital.
.
The hospital was founded by Rose A. M. Harley. The Harley Hospital was incorporated April 12, 1919 and dissolved October 19, 1983. The building was vacant before 1977.
From Tracey Flynn:
I am writing to you to share pictures of the Harley Hospital with the Dorchester Atheneum website and the Dorchester Historical Society. My cousin (Sarah Watmough) has brought this site to my attention and I?m now documenting a family history and thought I’d share these photos.
