Still Pittsburgh’s largest hotel, this opened in 1959 as the Pittsburgh Hilton. It was designed by William Tabler, the Hilton company’s pet architect. Originally it was, as James D. Van Trump told us in The Stones of Pittsburgh, “partially sheathed in panels of gold anodized aluminum, very appropriate to a luxury hotel.” The panels have been painted over.
The addition to the front opened in 2014; it does not seem to go with the rest of the building.
