Henry Hornbostel was one of the first architects to employ polychrome terra cotta. Here are three different patterns from buildings at Carnegie Tech, now Carnegie Mellon University.

Thistles, in tribute to Andrew Carnegie’s Scottish pride.

A Tudor Gothic building that fits well with Old Main and the chapel across the street. The cornerstone was laid in 1922 by Archbishop Canevin himself (Pittsburgh was not an archdiocese, but Canevin was titular Archbishop of Pelusium).
Like many Pittsburgh buildings, Canevin Hall has more than one ground floor.
College Hall was built in 1970, two years after Mellon Hall across the way, and we notice that the architect (whose name old Pa Pitt was not immediately able to find) took the idea of stilts from Mies Van der Rohe and applied it to an otherwise very different style of modernism. Although every element is indubitably twentieth-century, the whole effect gives us the impression of a classical temple. The interior is drab and utilitarian, but the exterior has a restrained dignity that is very attractive.
Duquesne University has overrun many blocks that were once crowded Bluff streets. The Academic Walk follows the course of what used to be Vickroy Street, and by almost random chance two Bluff rowhouses have been preserved in beautiful condition by the Spiritan Campus Ministry. In fact, on Google Maps we find that their address is still 952 Vickroy Street, even though they are the only remaining trace of Vickroy Street. In the 1800s, their neighbor used to be a brickyard, so the neighborhood has improved since they were built.
Many styles of buildings have been put up on the campus since Henry Hornbostel laid out the original plan for Carnegie Tech, but it’s remarkable how much the original Hornbostel plan has been respected. The campus is still built around these broad open green spaces, with the various buildings kept within matching heights and setbacks, even when they are in wildly different styles.
The Richard King Mellon Hall of Science was designed by Ludwig Mies van der Rohe, and is therefore a black box on stilts. Old Pa Pitt sometimes makes fun of Mies’ black boxes on stilts, but he means it good-naturedly. The colonnades of stilts have a job, and they do it well. They humanize some inhumanly large buildings by creating a human-sized interface between building and street. They also create an expansive outdoor space that is out of the rain and snow, but still open to the world. Here we see a good use of that space, with tables being set up for graduation festivities.
Built to be an inspiring showcase of the world’s best traditions in art, the College of Fine Arts building was positioned at the top of the Mall, as if the arts might be of some importance even in a technical school.
Niches along the front of the building pay tribute to various architectural and sculptural traditions.
