Wesley W. Posvar Hall

At 744,695 square feet (69,184.4 m2) it is the largest academic-use building on campus, providing administrative offices, classrooms, lecture halls, a food court, and computer labs.

The central area of the interior space is called the Galleria and contains various artwork including Virgil Cantini's mural Enlightenment and Joy and one of Samuel Pierpont Langley's aerodromes.

[chronology citation needed] The building incorporates many reminders of the famous ballpark—the home plate of Forbes Field remains near its exact spot, protected under plexiglass.

[11] The sculpture was donated to the university by the Joseph Horne Company from its department store in the South Hills Village mall where it had previously been on display.

[3] Tony Smith's 1971 20-foot-tall (6.1 m) painted steel sculpture Light Up!, commissioned by Westinghouse and originally displayed in downtown Pittsburgh,[11] can be found outside Posvar Hall, between it and Hillman Library.

[12] Donated to and re-installed at Pitt in 1988, it was temporarily loaned to the Museum of Modern Art and displayed in front of the Seagram Building in New York City for a 1988 Tony Smith retrospective.

The Aerodrome was an experimental aircraft commissioned by the United States Army from former Pitt professor and Smithsonian Institution Secretary Samuel Langley.
