Father Pitt

Henry Hornbostel’s only real skyscraper was briefly the tallest thing in Pittsburgh when it opened in 1929, before being surpassed two years later by the Gulf Building. It’s famous for the air beacon on top—red until recently, but now green to match the logo of the Huntington Bank—that flashes “Pittsburgh” all night in Morse Code. Behind and to the left, the building with three enormous arches is Hornbostel’s City-County Building.
