It was begun in 1888 and completed in 1891.","why_significant":"The nomination argues the building is a city landmark and a key element of the streetscape along West Fourth Street, one of the city's principal thoroughfares. Its tower, massing, fenestration and detailing are said to give it monumentality and quality of design that rank it among the most notable governmental buildings of its era. It is described as well maintained and little altered, with its design, urban qualities and fine construction regarded as irreplaceable.","narrative":"Built between 1888 and 1891 in Williamsport, the post office occupies an entire city block at a major intersection in the central business district. Its walls are faced with rough-faced gray limestone ashlar, with dressed stone architraves, belt courses and balconies, and its roofs are covered with dark gray slate accented by copper. A six-story tower rises above the West Fourth Street facade and marks the building's presence in the streetscape. Construction was designed under William A. Freret, Supervising Architect of the Treasury. The interior retains original fabric, including marble floors and paneled wooden wainscoting, and a courtroom extends across the east end of the second story. Local residents noted that construction costs came in below the amount appropriated. The building is valued for its monumental design, its urban setting and its high-quality construction, which the nomination treats as an irreplaceable architectural resource for the city.","period_of_significance":"1888-1891","architect_builder":"William A.
