Located across Forbes Avenue from Pitt’s Cathedral of Learning, the Carnegie complex was a gift to the city of Pittsburgh from Andrew Carnegie in 1895. The complex contains the region's main public library, a music hall, a fine arts museum, and a natural history museum. A unique view of the natural history museum’s world-famous dinosaur hall can be seen through the windows in the second-floor stacks of the library. University of Pittsburgh students may show their valid Pitt IDs and visit the museums free of charge.
A replica of the natural history museum’s Diplodocus carnegii (named after Andrew Carnegie) was unveiled on the lawn of the Carnegie complex in 1999. “Dippy's" long neck often is decorated with various scarves, depending on the seasons, and on some Panthers game days Dippy sports a blue-and-gold scarf to honor its neighbor, Pitt.
