It has since been converted to the John K. Tener Library.","why_significant":"The nomination argues the building is a locally outstanding example of early twentieth century public building architecture in the Classical Revival style, unusually monumental for a small town. It is also presented as representing the role of federal government administration in small communities and as an important local center of government services. Its integrity is described as excellent.","narrative":"Built between 1909 and 1912 as a federal post office, this two-story granite building stands on sloping ground near the centre of Charleroi's business district, set back fifteen feet from Fallowfield Avenue. Its seven-bay front has Tuscan pilasters and columns framing a recessed entrance portico, and the copper-clad doors are topped by a grille of superimposed squares and diagonal crosses. A parapet rises in a ziggurat over the south elevation and the carved entablature reads \"United States Post Office.\" Inside, the former workroom and lobby retain oak woodwork, plaster walls, original gaslight fixtures converted to electric, and an attic walkway with peepholes used by postal inspectors. Its scale stood out in a town of small lots and modest brick buildings. The building is valued for its high-style Classical Revival design, its well-preserved interior and exterior, and its link to federal government presence in the Monongahela Valley. Its construction is linked to John K. Tener, a local banker who later served in Congress and as governor.","period_of_significance":"1909-1912","architect_builder":"James Knox Taylor, Supervising Architect, Treasury Department; George Stiles, Construction Company; E.C.
