One South Broad, also known as the Lincoln-Liberty Building or PNB Building, is a 28-story 472 feet (144 m) office tower in Center City, Philadelphia, Pennsylvania, United States. The art deco tower, designed by architect John Torrey Windrim as an annex for Wanamaker`s department store, was completed in 1932. Wanamaker`s Men`s Store opened in the first seven floors of the building, which is located a block from Wanamaker`s main store, and was intended to rival European department stores with its size and selection. In 1952, the Philadelphia National Bank (PNB) bought the building and converted it into offices and banking space. The building`s bell tower is decorated on all four sides with PNB`s initials in stainless steel 16 feet (4.9 m) tall; the signs remain despite the bank`s later renaming and several mergers. Wells Fargo is the main tenant, occupying almost half the building. The former banking space at street level was converted to retail and restaurant space in 2000.
