The U.S Post Office Building, featured at the lower right of the photo, is a massively scaled public building designed by architect Rowland Gilchrist, under the direction of the U.S. Department of Treasury- James A. Wetmore, Acting Supervising Architect. The two-story building is noted for its Beaux Arts detailing and Neoclassical style, and it is reminiscent of turn-of-the-century federal buildings in Washington, D.C. The building is constructed of sandstone and concrete ashlar masonry and retains its original exterior wood windows. The interior lobby is a two-story space covered with a massive paneled dome and a stained-glass skylight. Polished marble walls, ornamental grilles of bronze and the original postal boxes adorn the interior. The lobby's ceramic tile floor dates from 1960, and covers the original marble floor with depictions of eight commemorative U.S. Postage stamps. The building has been in continuous operation as a post office since it opened in 1918. Continue westward on Mills Avenue.
