ending the prospect of completing the set.

The Pine Street Baptist Church in Providence, Rhode Island was opened in 1917 at Lloyd and Wayland Street as Central Baptist and in 2003, became known as Community Church of Providence. Between 1917 and 2018 the church featured a large Tiffany stained glass memorial to Frederick W. Hartwell that was created by Agnes F. Northrop and entitled "Light in Heaven and Earth". The complex work, considered "one of the largest and finest landscape windows ever produced by Tiffany Studios", largely was overlooked in the community. In 2018, the church sold the window to the Art Institute of Chicago. After conservation and preparation it will be displayed prominently as the Hartwell Memorial Window. Significant collections of Tiffany windows outside the United States are the 17 windows in the former Erskine and American United Church, now part of the Montreal Museum of Fine Arts in Montreal, Canada, and the two windows in the American Church in Paris, on the Quai d'Orsay, which have been classified as National Monuments by the French government; these were commissioned by Rodman Wanamaker in 1901 for the original American Church building on the right bank of the Seine. The Haworth Art Gallery in Accrington, England contains a collection of more than 140 examples of the work of Louis Comfort Tiffany, including vases, tiles, lamps, and mosaics.
