The complex includes the station building, the Rotunda cabstand, and the site.","why_significant":"The nomination argues the station is Pittsburgh's first work by D. H. Burnham & Company and its only example of the 'Burnham Baroque' style. It also cites the station's role as a gateway to the city during the peak days of the railroad and its location at the intersection of the railroad lines with the Golden Triangle.","narrative":"Built between 1898 and 1903 by D. H. Burnham & Company, this twelve-story Beaux-Arts neo-Baroque building of brick and terra cotta on a steel frame houses a large main-floor waiting room measuring 160 by 70 feet, arcaded with glazed terra cotta pillars and plaster vaults. Floors three through twelve hold railroad offices arranged around an open rectangular court beneath a glass roof. The station sits at the northern apex of Pittsburgh's Golden Triangle, where Liberty Avenue and Grant Street meet, and a brick ramp rises from that intersection to the Rotunda cabstand and the platforms beyond. Its design is considered one of the firm's notable Pittsburgh works, and the nomination treats the station, cabstand and site together as a single historic entity. The complex served as a gateway to the city during the railroad's peak years. Its central location has made the site important to later transportation planning, and the building's plan is noted as suited to conversion to a hotel.","period_of_significance":"1898-1903","architect_builder":"D.
