Steel Plaza Subway Station
Steel Plaza was designed in the 1980s, and its architecture is an interesting combination of Brutalist and Postmodern styles—the two most prominent materials are raw concrete and polished granite. It was built as a junction station, where the main subway line met the spur to Penn Station, which is not in regular service these days. In the picture below, the main line is on the left, and the spur is on the right.

Bridge of Sighs
The Bridge of Sighs connected the Allegheny County Courthouse with the jail across Ross Street. Now it connects the bureaucracy in the courthouse with more bureaucracy in the repurposed jail building, so that the name is just as appropriate. In the picture above, for a bit of a change of pace, old Pa Pitt gives you a bus driving away from you, which gives us a good sense of scale.

Wood Street Building (300 Sixth Avenue Building)
A Daniel Burnham design built for the McCreery & Company department store, this building opened in 1904. It originally had a classical base with a pair of arched entrances on Wood Street, but beginning in 1939 it had various alterations, so that nothing remains of the original Burnham design below the fourth floor. This was one of Burnham’s more minimalistic designs; in it we see how thin the wall can be between classicism and modernism.
Below, an abstract composition with elements of this building reflected in Two PNC Plaza across the street.

United Steelworkers Building (IBM Building)
The diamond grid is not an ornamental facing: it holds up the building, along with a central core. “Diagrid construction” is a little more common today, but still fairly unusual; perhaps the most famous or notorious example of it is the Gherkin in London. This was a very early example. It was finished in 1964, and although it was originally built for IBM, it fits its current owner very well: its steel grid is a good demonstration of what steelworkers are capable of. The architects were the New Orleans firm of Curtis and Davis.

One Oliver Plaza
This is not Father Pitt’s favorite building downtown, but it was one of the last works of a distinguished modern architect: William Lescaze, who died in 1969, the year after One Oliver Plaza was built. The building has had several names since then; it now goes by the name K&L Gates Center. Old Pa Pitt’s friend Dr. Boli has remarked that the names at the tops of the skyscrapers are a good index of who is most ruthlessly exploiting the masses at the moment. K&L Gates is a gigantic law firm.

Maginn Building
The Maginn Building was put up in 1891, just three years after H. H. Richardson’s Allegheny County Courthouse opened. Even before the courthouse was finished, it had already created a mania for the “Richardsonian Romanesque” style in Pittsburgh, and the versatile Charles Bickel was happy to come through for any client who wanted an impressively Romanesque building.
