The ground-floor storefront was replaced at some time in the modernist era, but the upper two floors preserve two-thirds of a fine terra-cotta front.

Originally called the McCance Block after its owner, this came to be known as the Triangle Building for obvious reasons. As Father Pitt has mentioned before, it fills what may be one of the smallest downtown city blocks in the country, so that every side of a relatively small building faces the street.
Andrew Peebles was probably the architect—but old Pa Pitt has not sorted that out completely yet, because he has also heard of Thomas Scott as the architect. His current hypothesis is that the building rose in two stages: the first four floors by Peebles, and the top two floors, which are simpler and built with brick of a very slightly different shade, by Scott some years later. The building has recently been refurbished for (you guessed it) luxury apartments.




Trowbridge & Livingston, Andrew Mellon’s favorite architects, designed this block-long palace of finance. The legendary interior was destroyed in the 1990s for a blink-and-you-missed-it department store, but the exterior is almost completely unchanged from the day the building opened in 1925.

The spire of the German Evangelical Protestant Church (now Smithfield United Church of Christ), designed by Henry Hornbostel and finished in 1926, was the first structural use of aluminum. Behind it, the Alcoa Building, designed by Harrison & Abramovitz and finished in 1953, was the first skyscraper entirely clad in aluminum.

Here is a remnant of the old middle-nineteenth-century commercial Pittsburgh, when a large part of the population lived downtown and shopkeepers often lived above their shops. In addition to being an unusual relic of the mostly obliterated past of downtown, this particular building is famous for its mural, “The Two Andys,” by Tom Mosser and Sarah Zeffiro.


The Chamber of Commerce Building seems to be neglected in Pittsburgh lore; nobody mentions it, and in fact the Skyscraper Page Pittsburgh skyscraper diagram skips right over it, ignoring it completely, though the diagram includes a number of considerably smaller and shorter buildings. Even old Pa Pitt has never featured this building before, mostly because it is difficult to get a picture of the whole building. So here is an illustration of the building when it was new; it has changed very little. It is easier to pick out details with a versatile lens, so here are a few of the interesting decorations. The architects were Edward B. Lee, who moved his office into the building when it was finished, and James P. Piper.





Now the Smithfield United Church of Christ, and it has had several other names. This lacy spire has an honored place in history as the first structural use of aluminum. (The aluminum point on the Washington Monument was just a lump of aluminum set on top, not a structure.) The architect Henry Hornbostel’s other experiment in this building, the use of decorative concrete panels on the exterior walls, has not held up as well; for years the rest of the building has been shrouded in netting to prevent bits of concrete from raining on pedestrians. Below is a picture Father Pitt took of the tower in 2000, before the shrouds went up.


The giant Kaufmann’s department store grew in stages over decades. This part of it was designed by Charles Bickel, who decorated it with exceptionally fine terra-cotta ornaments.





First put up in 1913 (replacing a clock on a post that had stood here earlier), the Kaufmann’s clock is one of the famous sights of Pittsburgh. It keeps time, too.



Built in 1971, this is now number 23 on the list of tallest buildings in Pittsburgh. The architects were the venerable Chicago firm of A. Epstein and Sons.
To make a more realistic-looking rendition of the building than is optically possible, old Pa Pitt adjusted the perspective on two planes. This adjustment has comical effects on the background, but the main subject looks natural now.
