Allerdice, Taylor, High School

Why it's listed
Taylor Allderdice High School is a four-story Neo-Classical school on Shady Avenue in Pittsburgh's Squirrel Hill neighborhood, designed in 1927 by architect Robert Maurice Trimble. Its H-shaped plan has a central pavilion with a three-story portico supported by six colossal columns, and two five-bay end pavilions defined by buff brick pilaster strips. Inscriptions on the end pavilions read "The Highest Aim of Education is Forming Character" and "The Foundation of a State is the Education of its Youth." The building includes three gymnasiums, a competition-length swimming pool with blue tile walls, and shop classrooms in a one-story rear wing. Trimble, a Pittsburgh-born architect who trained under Frederick J. Osterling, also designed the Perry Traditional Academy. The school is named for Taylor Allderdice, a steel-industry executive and charter member of the consolidated school board. It was the last Pittsburgh high school built for nearly fifty years and is regarded as remarkably intact.
Significance in brief: The nomination describes the school as the last high school built in Pittsburgh for nearly fifty years, until Brashear High School was completed in 1976. It is described as remarkably intact, with a building plan and facilities that offered the latest educational opportunities of its period. Its alumni are said to include many of Pittsburgh's influential citizens.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
