All six sides of the two-story steel frame building are faced in brick laid in Flemish bond. The entrance terrace is granite, paved with bluestone and using limestonecoping, flanked with iron lampposts. The middle three of the five bays are recessed to allow for the limestone enframements around the double doors. Each window bay is topped by a roundel and bronzegrille in an abstract eagle form. "United States Post Office" is spelled out by bronze letters between the roundels, and "Mineola, New York" is carved into the frieze above the main entrance. The entire structure is topped by limestone coping and a flat roof. The interior retains the original pink Tennesseemarblewainscoting with a dark marble baseboard. The walls above the marble are plaster with a moldedcornice between them and the ceiling. The floor is terrazzo with embedded brass strips dividing it into areas of different color. Unusually for a post office of this size built during the 1930s, there is no mural or other artwork of the type commissioned by the Works Progress Administration in the lobby.
History
Mineola was already a central community of a primarily agricultural area when it was chosen as the seat of the newly formed county in 1899. In the early decades of the next century, improvements to rail and road transport led to the beginning of suburbanization in Nassau County and the Mineola area. The growth required, among many other things, new postal facilities. In 1931 an amendment to the Public Buildings Act of 1926 authorized the construction of 136 new post offices in New York. Sixteen of these were to be in Long Island, including Mineola. The site was purchased in 1933, and Peabody, Wilson & Brown, a New York firm best known for some large estates on Long Island such as Charles Millard Pratt's Seamoor in Glen Cove and the HuntingtonTown Hall. A.J. Paretta Contracting of Long Island City began work in 1935, finishing the following year. The Mineola post office is the only federal commission the Peabody Wilson firm is known to have undertaken, and one of its last. Julian Livingston Peabody and his wife drowned in January 1935 in the sinking of the passenger liner SS Mohawk off New Jersey, and Archibald Manning Brown left the firm that same year to head the design team planning the Harlem River Houses, the first federally financed housing project in New York City.
Aesthetic
The Colonial Revival style had been popular for new post offices in New York from 1905 on, when the Geneva post office in the Finger Lakes region became the first in the state to use it. It was heavily used in the 1920s and later on in the 1930s, when new construction intensified as the government tried to alleviate the effects of the Great Depression. With a few exceptions, elements of Colonial buildings were used without trying to emulate any specific building. Aspects of the Mineola post office that most strongly reflect this are its entrance enframements, pediments, roundels and windows. The 1930s also saw the emergence of the Art Deco and associated modernist styles. These made their mark on the Mineola post office in its flat roof, broad limestone decoration and the absence of cornices at the roof line. The abstracted eagle shapes in the roundel grilles are also another touch more in keeping with modernism than Colonial Revival.
