The original campus of the University of Michigan was nearly a perfect square about a half-mile along a side. A street-sized walk, appropriately called the Diag, runs diagonally across this square, connecting its southeast and northwest corners. In 1904 a new engineering building was either started or finished (I do not remember which) to house classrooms. When another engineering building was built on the expanded campus across the street from it many years later, the old building came to be known as West Engine, to distinguish it from the new East Engine. Old West Engine is (or maybe by now, was) a four-story, L-shaped structure that stood at the southeast corner of the original campus.
