In the late 19th century, numerous charitable institutions influential in setting social policy were located on 23rd Street, and some, such as the Federation of Protestant Welfare Agencies, still remain in the area. Calvary Church on Gramercy Park North has a food pantry that opens its doors once a week for one hour, and the Brotherhood Synagogue on Gramercy Park South served as an Underground Railroad station before the Civil War, when the building was a Quaker meeting house, established in 1859.
