Berkeley’s elegant Main Post Office is representative of the Second Renaissance Revival style, also called Neo-Classical Renaissance Revival. Government buildings constructed in this era were designed to “educate and develop the public taste and eventually elevate it to a higher plane.” Classical motifs decorate the building’s exterior and interior. The exterior terra cotta arches that are supported by plain tuscan columns are repeated on the inner wall of the loggia and again in the wall between the lobby and the main workroom. The mural over the door of the original Postmaster’s office, which depicts figures from California’s Spanish and pioneer periods, was painted in 1936–1937 by Suzanne Scheuer for the Treasury Relief Art Project during the Depression.
