Tour Mary Baker Eddy’s first home of her own. It was here that Mrs. Eddy (the founder of Christian Science) completed the first edition of her major work, “Science and Health with Key to the Scriptures.” In this house she laid many of the foundations of the Christian Science movement, including the formation of her church. This Italianate-style house was practically new when she purchased it, and it has been recently restored inside and out to its original look and feel.
