Pittsburgh Central Downtown Historic District
Also known as: See Also:Frick Building; US Post Office and Courthouse

Why it's listed
Downtown Pittsburgh's central business district holds this cluster of commercial and institutional buildings, mostly dating from the 1870s through the 1930s and organized around Grant Street and Mellon Square. The district contains four churches built between 1870 and 1925 in several Gothic Revival modes, including Trinity Cathedral, whose churchyard holds graves from the late eighteenth century. Banking is represented by the Mellon Bank building, the German National Bank, and the Federal Reserve Bank of Cleveland. Major office towers include the 1901 Frick Building, the 1896 Park Building, and the 1930s Koppers and Gulf Buildings. The William Penn Hotel, Kaufmann's department store, and the Union Arcade of 1915 add retail and hospitality uses. The 1950s Alcoa Building is notable for its aluminum construction, and Mellon Square is described as a notable example of mid-century urban open space.
Significance in brief: The nomination argues the district is the foremost concentration of major late nineteenth and early twentieth century institutional and commercial buildings in downtown Pittsburgh. It includes churches, banks, department stores, office towers, and a hotel, many designed by nationally prominent architects. It also represents the growth of Pittsburgh's industrial economy and the corporate office era, and the 1950s Renaissance-era Alcoa Building and Mellon Square are presented as notable contributions.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
