Building Description:

Construction started in 1904 and the building opened in April 1905.  Designed by MacClure and Spahr, a Pittsburgh firm that gave us several other distinguished buildings, including the Union National Bank building on Fourth Avenue in Pittsburgh’s Financial District. The Diamond Bank became Pittsburgh National Bank, which in turn became PNC. It still stands as an office building, no longer owned by PNC, even as skyscrapers crowd around it.
