In 1915, Mary Longyear, a faithful follower of Mary Baker Eddy and the Christian Science faith, purchased the land from the Lyman Estate in Brookline, Massachusetts, and donated to the Christian Science Church. Planning began immediately to build a facility as a temporary resort where those seeking relief through Christian Science may go to find practical assistance in overcoming their difficulties. The need for a hospital/sanatorium was established by Mary Baker Eddy as early as 1906, and it would be over a decade before this need was filled. The complex was built in stages beginning in 1918 with this building, the main building, observation tower and a powerhouse designed by Clarence T. McFarland. The buildings were designed in the Tudor Revival style, blending in with the many country estates in this section of Brookline. The complex would train nurses and treat patients for over 100 years and remains an important institution into the 21st century.
