A small school by a distinguished architect: Charles M. Bartberger, who gave us several fine schools. (He is often confused with his father, Charles F. Bartberger, who designed some prominent churches.) The Lee School is now a retirement home under the name Gualtieri Manor.
The entrance is surrounded by tasteful terra-cotta ornamentation.
This pattern is called a Vitruvian wave, named for Vitruvius, the ancient Roman author whose manual on architecture became the arbiter of everything that was proper in design during the Renaissance.
The arms of the city of Pittsburgh over the entrance.
