Pittsburgh Central Downtown Historic District (Boundary Increase)
Why it's listed
Downtown Pittsburgh's central business district holds this concentration of commercial and institutional buildings, mostly dating from the 1870s through the 1930s. The district includes four churches built between 1870 and 1925 in several Gothic Revival modes, including Trinity Cathedral, whose churchyard holds graves from the late eighteenth century. Banks, department stores, hotels and office towers line Grant Street and nearby avenues. The Frick Building of 1901 was among the first slab skyscrapers in the city, and the Koppers and Gulf Buildings of the 1930s show Art Deco detailing. The William Penn Hotel, Union Arcade and Kaufmann's store are among the notable works. Mellon Bank and the Mellon family's financial history are central to the district's story. Its significance rests on the density and variety of these buildings, many of them designed by nationally known architects, and on their role in Pittsburgh's growth into a major industrial city.
Significance in brief: The nomination argues that the district is the foremost concentration of major late nineteenth and early twentieth century institutional and commercial buildings in downtown Pittsburgh, including churches, banks, hotels, department stores and office towers. It cites the work of nationally prominent architects and the role of the Mellon, Frick, Carnegie and Kaufmann families in shaping downtown development. The Alcoa Building and Mellon Square are presented as landmarks of the 1950s Renaissance era, with their significance tied to their aluminum construction and their innovative urban open space.

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).
