The original building was constructed beginning in 1931.","why_significant":"The nomination argues the building is significant for its Classical design with Art Deco motifs, which encloses what it describes as one of the Pittsburgh public schools' most ornate interiors, especially the east entry hall and auditorium. It also notes the playing field and grandstands as the school's most recognizable feature.","narrative":"Built from 1931 on part of the former Allegheny Arsenal site in Pittsburgh's Lawrenceville section, the school was designed by the firm Schwab, Palmgreen, & Merrick and faces busy Butler Street. Its roughly C-shaped plan wraps around a playing field set at basement level, with a four-story central spine and projecting wings. The primary facade has fluted pilasters, a stone entry surmounted by an eagle, and pedimented end bays bearing the seal of Pittsburgh. Linking elements feature arched openings with carved keystones and Art Deco panels. The interior is most elaborate in the east entry hall and auditorium, which have patterned terrazzo floors, marble walls and wainscoting, a stage surround with eagles and urns, and six octagonal metalwork chandeliers. The west wing was added in 1939 for an elementary school, and the building later served the Girls' Vocational High School from 1952 to 1969. The nomination treats the Classical design, Art Deco detailing and auditorium interior as the basis for its significance.","period_of_significance":"1921-1940","architect_builder":"Schwab, Palmgreen, & Merrick (architects for the original building); Marion M.
