English: Built in 1926-1934, this Gothic Revival-style tower was designed by Charles Klauder to serve as an administration building and classroom building for the University of Pittsburgh. The building stands 42 stories and 535 feet (163 meters) tall, being the second-tallest university building in the world, only exceeded by the newer Moscow State University Main Building in Russia, and was the second-tallest building in Pittsburgh at the time of its completion, though it lost this status in 1970. The building is clad in limestone with a massing that tapers towards the top and center with multiple setbacks, a four-story podium at the base with bay windows and tall recessed gothic arched entrance bays, buttresses and tracery on the exterior facade, pinnacles and a parapet with multiple gothic arches at the top of the building, a theater to the southeast of the main building with similar exterior features but a much lower height, known as the Stephen Foster Memorial, and a series of themed classrooms with various decorative finishes inside the building. The building was listed on the National Register of Historic Places in 1975, and is a contributing structure in the Schenley Farms Historic District, listed on the National Register of Historic Places in 1983. The building today remains the principal structure of the University of Pittsburgh campus, dominating the surrounding Oakland neighborhood, and standing in the middle of a large lawn with trees and smaller buildings at the edges.
