History and Architectural Features

The U.S. Custom House was built in 1867-1872 on the site of the city's first Custom House. The need for a new Custom House was exacerbated by the Great Fire of July 4, 1866. The fire destroyed the Exchange Building - which had previously housed the customs office, post office, and courts - as well as 1,800 other buildings in the center of the city. The U.S. Custom House has experienced only minor changes since it was constructed, and therefore exhibits a high degree of architectural integrity. The majority of the building's distinctive elements, such as the marble checkerboard floors and decorative staircases remain in place. In 1998, the aluminum doors, which were installed during the 1960s at the main entrances, were replaced with wooden doors similar in design and color to the original doors to the building.
