Independence Hall - Preservation

Preservation

From 1802 to 1826-27, artist Charles Willson Peale housed his museum of natural history specimens (including the skeleton of a mastodon) and portraits of famous Americans, on the second floor of the Old State House and in the Assembly Room.

In early 1816, the Commonwealth of Pennsylvania sold the State House to the City of Philadelphia, with a contract signed by the governor. The deed, however, was not transferred until more than two years later. Philadelphia has owned the State House and its associated buildings and grounds since that time.

In 1948, the building's interior was restored to its original appearance. Independence National Historical Park was established by the 80th U.S. Congress later that year to preserve historical sites associated with the American Revolution. Independence National Historical Park comprises a landscaped area of four city blocks, as well as outlying sites that include: Independence Square, Carpenters' Hall (meeting place of the First Continental Congress), the site of Benjamin Franklin's home, the reconstructed Graff House (where Thomas Jefferson wrote the Declaration of Independence), City Tavern (center of Revolutionary War activities), restored period residences, and several early banks. The park also holds the Liberty Bell, Franklin's desk, a portrait gallery, gardens, and libraries. A product of extensive documentary research and archaeology by the federal government, the restoration of Independence Hall and other buildings in the park set standards for other historic preservation and stimulated rejuvenation of old Philadelphia. The site, administered by the National Park Service, is listed as a World Heritage Site by UNESCO (joining only three other U.S. man-made monuments still in use, the others being the Statue of Liberty, Pueblo de Taos, and the combined site of the University of Virginia and Monticello).

Independence Hall and the Liberty Bell are now protected in a secure zone with entry at security screening buildings. Following the September 11, 2001 attacks, as part of a national effort to safeguard historical monuments by the United States Department of Homeland Security, pedestrian traffic around Independence Square and part of Independence Mall was restricted by temporary bicycle barriers and park rangers. In 2006, the National Park Service proposed installing a seven-foot security fence around Independence Hall and bisecting Independence Square, a plan that met with opposition from Philadelphia city officials, Pennsylvania Governor Ed Rendell, and Senator Arlen Specter. As of January 2007, the National Park Service plan was revised to eliminate the fence in favor of movable bollards and chains, and also to remove at least some of the temporary barriers to pedestrians and visitors.
