The Federal area was defined by an act of the Congress (Public Law 795, 80th Congress) after the matter had been studied intensively by a Federal commission named in 1946. The principal area covers three city blocks between Walnut and Chestnut from Fifth to Second Streets, with subsidiary areas on either side to include important historic sites, such as the property adjacent to old Christ Church, the site of Franklin’s home, and an area leading from Walnut Street to old St. Mary’s Church. A surprising number of significant buildings are included within the park boundaries. The First and Second Banks of the United States, the Philadelphia Exchange, and the Bishop White and Dilworth-Todd-Moylan houses are the principal historic buildings included in the Federal area. Carpenters’ Hall and Christ Church will not be purchased, but their preservation and interpretation have been assured through contracts with the Department of the Interior. [Illustration: _A scene from the reenactment of the signing of the Declaration of Independence in the Assembly Room of Independence Hall on July 4, 1951._] The contribution of the City of Philadelphia to the historical park is by far the most vital. On January 1, 1951, the custody and operation of the Independence Hall group of buildings and the square were transferred, under the terms of a contract, from the City to the National Park Service. The title to the property will remain with the City. Earlier, in 1943, the buildings were designated a national historic site by the Department of the Interior. Since assuming custody of the Independence Hall group, the National Park Service has carried out an extensive program of rehabilitation of these historic structures; also, many facilities for visitors have been provided for the dissemination of the history of the Independence Hall group, as well as that of the other structures in the park. In addition, a far-reaching project of historical and architectural research has been undertaken. The facts gathered in this research will enable plans to be developed which will assure the public of deriving the maximum benefit from a visit to this most important historical area. It is fortunate that these old structures have survived, sometimes through accident rather than design, so that they may serve as tangible illustrations of this Nation’s history for the inspiration of this and succeeding generations of Americans. _The Story of a Symbol_
