US Post Office-Olean
Also known as: Olean Post Office

Why it's listed
Olean's post office, at South Union and West State Streets, was built between 1910 and 1912 to designs overseen by James Knox Taylor, Supervising Architect of the Treasury. The two-story building has a tan pressed-brick exterior over a granite foundation, with five round-arched openings across the front, limestone trim and a hip roof. Its frieze of colored trim and diagonal brick with diamond panels sits beneath a carved wooden bracketed cornice with exposed rafters. That wood cornice is unique among Taylor's New York post offices, which mostly follow Classical models with stone or terra-cotta cornices. The Renaissance-inspired detailing also echoes the neighboring 1909 public library. Inside, the lobby keeps its high ceiling, modillioned cornice, oak woodwork, paneled wainscoting and cast-iron stairs. The federal government bought the site in 1909, and the project cost $79,540. A 1950s rear addition is the main later change to the building.
Significance in brief: The nomination argues the building is architecturally significant as a distinguished example of early twentieth-century public architecture in New York State. It is a late and unusual work by Taylor, mixing Italian Renaissance and Craftsman motifs, with a carved wood cornice and decorative brick frieze unique among his New York post offices. Its styling also complements the adjacent 1909 Olean Public Library.

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.
