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.

Andrew Peebles, who also designed St. Peter’s on the North Side, designed this church, which was quite large when it was built but looks like a toy next to the skyscrapers of Grant Street. Built in 1887, it is now the oldest building on the street.

George Schwan was the architect of this building, according to a city architectural survey. Its modernistic classicism makes it a good neighbor to a wide variety of architectural styles. From a distance, it gives us the impression of an all-stone building, but in fact the effect is achieved with a carefully balanced mixture of terra-cotta tiles and stone-colored brick.

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.


A few details of the Union Trust Building, designed by Pierre A. Liesch when he was working for Frederick Osterling—at least according to Liesch; the building is usually just credited to Osterling.




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.





This building stands out among the skyscrapers that surround it like a strange relic of a lost civilization—the pre-skyscraper age. It was built in 1890, and the architect was young Frederick Osterling. He would soon master the Richardsonian Romanesque style and become one of our most accomplished practitioners of it, but this is pre-Richardsonian Romanesque. The weighty but graceful eyebrows over the arches, the complex and irregular rhythm of different sizes, and the surprising but flowing curves all remind us of Osterling’s old master Joseph Stillburg, whose Romanesque ideas went back to his native Austria.
