Society Hill is a historic neighborhood in Center City Philadelphia, with a population of 6,215 as of the 2010 United States Census. Settled in the early 1680s, Society Hill is one of the oldest residential neighborhoods in Philadelphia. After urban decay developed between the late 19th and early 20th centuries, an urban renewal program began in the 1950s, restoring the area and its many historic buildings. Society Hill has since become one of the most expensive neighborhoods with the highest average income and second-highest real estate values in Philadelphia. Society Hill's historic colonial architecture, along with planning and restoration efforts, led the American Planning Association to designate it, in 2008, as one of the great American neighborhoods and a good example of sustainable urban living.The neighborhood hosts one of the largest concentrations of original 18th- and early 19th-century buildings in the United States. Society Hill is noted for its Franklin street lamps, brick sidewalks, cobblestone and Belgian block streets bordered by two- to four-story brick rowhouses in Federal and Georgian architecture, and public buildings in Greek Revival architecture such as the Merchants' Exchange Building and the Old Pine Street Church.

Thaddeus Kosciuszko National Memorial, at 301 Pine Street in Philadelphia, Pennsylvania, preserves the home of Tadeusz (Thaddeus) Kościuszko. The life and work of the Polish patriot and hero of the American Revolution are commemorated here. Kosciuszko returned to the United States in August 1797 to a hero's welcome after his wounding, capture, imprisonment, and banishment from his native Poland, which was partitioned by three neighbouring powers. Kosciuszko's secretary, Julian Ursyn Niemcewicz, having been instructed to find "a dwelling as small, as remote, and as cheap" as possible, chose Mrs. Ann Relf's boarding house at the corner of 3rd and Pine Streets in Society Hill. Here, where Kosciuszko recuperated from his wounds while rarely leaving the house, he was visited by numerous luminaries of the day, including Vice President Thomas Jefferson, architect Benjamin Latrobe, Supreme Court Justice William Paterson, Chief Little Turtle of the Miami people, and Chief Joseph Brant of the Mohawk nation. He returned to Europe the following June to support the restoration of a divided Poland. The home was listed on the National Register of Historic Places on December 18, 1970.
