Carnegie Institute and Library
Why it's listed
Occupying more than eight acres in Oakland between the University of Pittsburgh and Carnegie Mellon University, the Carnegie Institute complex combines a turn-of-the-century cultural palace with a 1974 addition. The original 1895 Institute, now the Library, uses sandstone bearing masonry, while the 1904 addition is a steel frame clad in the same stone. Roughly 165,000 square feet of cut sandstone and 6,000 tons of marble were used. Its principal interiors include the Music Hall foyer with Giallo Antico marble columns, the Music Hall with a coffered half-dome ceiling, the main staircase hall with John White Alexander murals, and Architecture Hall, 125 feet square. Carnegie offered Pittsburgh a library in 1881, and his 1890 offer of a million dollars for a cultural center was accepted. The complex is regarded as the most significant cultural resource in the Pittsburgh area and is among the city's most visited attractions.
Significance in brief: The nomination argues the complex is significant for its association with Andrew Carnegie and the development of Pittsburgh, as the first notable example of his donations. It calls the building a prime example of the nineteenth-century cultural palace and an outstanding example of Beaux Arts design, and describes its interiors, especially the Music Hall foyer, as among the most splendid ceremonial halls in America.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
