Interesting tidbit shared by the OddPittsburgh Twitter page today. Below are early sketches of an ambitious master plan for the university in 1907. I believe this coincided with the name change from WUP to UPitt in 1908, when it bought the land in Oakland where the campus is to this day.
It says that it was eventually abandoned in favor of the Cathedral of Learning plan, which also had big aspirations early on. Very interesting how there was such a sharp change in the architectural designs, going from Greco/Roman to gothic.
There were actually 5 buildings built by Pitt in the plan, not including the current Allen Hall (still standing) which was the original Mellon Institute of Technology (then part of Pitt) building and was designed to fit the Acropolis plan style.
The building OddPittsburgh is missing is the original Trees Gymnasium (named after the same
Joseph Trees), which was originally located up by present day Sutherland Hall.
State, Thaw, and Pennsylvania Halls were realized closest to the intended design. However, only half of each of these buildings was finished (and why, for instance, the Panther murals seen from Pitt Stadium was able to be painted on the flat, unfinished side of Pennsylvania Hall). The Mineral Industries building was severely scaled back in ornamentation, as was Trees Gymn, due to funding.
Unfortunately, the most impressive part of the facade of Thaw Hall, which was the main entrance, was obscured/obliterated when the university shortsightedly grafted the Space Coordination Research Center onto it. By the way, you can orient yourself on the above Acropolis plan picture by locating the far right cross streets at the bottom which are present day O'Hara and Bigelow.
The first deviation from the Acropolis plan, other than simplification of designs due to funding, was Eberly Hall (originally named Alumni Hall), although it retained neo-classical elements, as did Pitt Stadium, it clearly deviated from the intended campus plan. That style of architecture officially ended on-campus with the Cathedral of Learning gothic campus plan, which produced 5 buildings including the Cathedral, all of which are still standing. Can you name them?
