Overbrook High School

Why it's listed
Overbrook High School is a public high school in Philadelphia, built between 1924 and 1926 to a Gothic design by architect Irwin T. Catharine. It was constructed as part of the Philadelphia School Board's expansion of its high school program, which had been a priority since the end of the nineteenth century and was financed by a $2,500,000 loan negotiated for site acquisition and construction. Earlier facilities in the same program included West Philadelphia High School, completed in 1911. The building is noted for its size and architectural detailing. Catharine's Gothic public schools in the city typically had ornate ornamentation and square towers. Overbrook differs from these, with less intricate detailing and conical piers. Its departure from his usual approach is part of what makes it distinctive. The school is regarded as an important example of Catharine's work and of Philadelphia's public school architecture of the period.
Significance in brief: The nomination argues the school is distinctive for its Gothic design and its impressive size and architectural detailing. It is presented as a notable example of the work of Catharine, described as a highly important architect of Philadelphia public schools. It is also placed within the expansion of the city's high school program in the early twentieth century.

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.
