The U.S. Custom House in Baltimore is located two blocks north of the
Inner Harbor, on a gently sloping site bounded by Gay, Lombard, and Water Streets. The six-story building, 92 feet high from base to roof balustrade, displays an axial symmetry and imposing presence characteristic of the Beaux-Arts style. The building's architects,
Joseph C. Hornblower (1848–1908) and
John Rush Marshall (1851–1927), began their careers in the
Office of the Supervising Architect of the
Treasury Department. They used Hornblower's training at the
École des Beaux-Arts and the experiences of their European tours to apply French academic planning and organizational principles to American civic architecture. The steel structure and masonry bearing walls are faced with granite quarried near
Laurel, Maryland, and
Mount Airy, North Carolina. The primary facade fronts Gay Street. A smooth-faced basement level (extending from grade up to a watertable course) rises to a heavily rusticated first floor. The second through fourth stories are articulated by three-story engaged
Ionic columns, flanking the recessed window bays. Alternating segmental and triangular pediments carried on consoles top the second-story windows. The smooth columns support a full entablature and roof balustrade, which wrap around the building and conceal the attic story and flat roof. The Gay Street entrance is approached by marble steps that are flanked by
plinths with wrought-iron lamp standards with lamps resembling 18th century ship's stern lanterns. The entrance doors are protected behind wrought-iron grillework. The west (Commerce Street) side of the building reveals an "E-shaped" plan. The double-story Call Room pavilion forms the middle arm of the "E" and is on axis with the entrance. Rusticated corners flank a five-bay window arcade. The window spandrels are decorated with carvings depicting sea monsters, shells, and other nautical ornamentation that reflect the Custom House's proximity to Baltimore's Inner Harbor. A balustraded parapet shields the copper-clad roof of the pavilion. The main lobby has a marble floor with an inlaid brass compass design. The walls are paneled with variegated marble. The lobby is flanked by elevators and stairhalls, with marble stairs and ornamental iron and brass railings. A narrow corridor connects the lobby to the historic Call Room where customs revenues were paid. The Call Room is the Custom House's most impressive, and historically significant, space. The walls have paired
Ionic pilasters supporting an
entablature with a paneled
frieze. The paneled cove rises to the central ceiling panel, measuring 63 feet by 30 feet, and adorned with a
mural entitled
Entering the Harbour. It depicts a fleet of ten sailing vessels: ships including a
whaler,
barks, a
barquentine, a
brig, and a
schooner entering the harbor. The panels of the
cove and
frieze, five
lunettes on the east wall, and the borders of the ceiling panel depict the evolution of navigation. They portray over 125 vessels, from ancient Egyptian ships to the
R.M.S. Mauretania of 1907, accompanied by
J. P. Morgan's yacht, the
Corsair. All of the murals were painted by
Francis Davis Millet, a prominent American muralist of the period. Millet died just a few years after these murals were completed, perishing along with over 1,500 others in the sinking of the
R.M.S. Titanic in 1912. After four years of renovation and modernization work, the Custom House formally reopened in 1997. ==Significant events==
