Amesbury Window Restoration Project The Mary Baker Eddy Historic House in Amesbury sheltered Mrs. Eddy on two occasions in the years immediately following her discovery of Christian Science. The house is currently undergoing a complete exterior restoration, including the windows. The cost of window restoration is just over $100,000. Two generous Longyear members have stepped forward to offer a $50,000 matching challenge grant for the project. Gifts to the window restoration fund will be matched dollar for dollar up to $50,000!
