This brick and limestone-faced former post office is a refined example of Beaux-Arts classicism. Despite its modest size, the compact, rectangular composition with a curved, corner entrance is decidedly urban and monumental. Significant features include the broken-pediment doorway, wall panels, and pilasters, balustrade, and large windows with muntins in an irregular grid pattern. Inside, the entrance vestibule is a flat-ceilinged rotunda. In 1938, the post office’s functions were moved to a new building (PR18) and this one repurposed for municipal services.
