Oswego City Library

Why it's listed
Perched on a hillside overlooking Lake Ontario, this brick library in Oswego was built in 1855-56 in the Castellated style. Gerrit Smith, a leading local citizen, gave $25,000 for the building and another $5,000 for books, and Hewes and Rose of Syracuse designed and built it. The east front has a central tower, corbelled side turrets, battlements and blank slits imitating medieval arrow openings, with round-arched windows and limestone trim over a shaley limestone foundation. Inside, a large reading room fills the main floor, while the top floor was left unfinished when costs ran over. Steel trusses were added in the 1930s to strengthen the structure. The nomination describes it as the oldest remaining public library building in New York State and notes that the exterior has survived without alteration. Adult classes for seamen, child care programs, two early church congregations and later the Oswego Art Guild all used the building, which still serves as a library.
Significance in brief: The nomination calls it the oldest remaining public library building in New York State and a rare early library. It is also an excellent example of pre-Civil War romantic taste, with a full range of castellated or Norman details. The exterior is largely unaltered, and the building has served as a centre of the city's educational and cultural life.

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.
