On July 5, 2015, Saint Mary's Episcopal Church closed after 175 years in operation; the Church of South India's Congregation of the Hudson Valley moved in that November.Scarborough Presbyterian Church, given to the community by Margaret Louisa Vanderbilt Shepard and her husband Colonel Elliott Fitch Shepard (who lived on the nearby Woodlea estate), was the first church in the United States with an electric organ.
