United States Customhouse, Custom house in Portland, Maine, United States

The United States Customhouse on Fore Street is a three-story granite structure with a hipped roof and decorative iron gallery railings framing its exterior. The building displays classic architectural details characteristic of its construction period and remains a notable presence on the street.

Construction took place between 1867 and 1872, following Portland's Great Fire that devastated the city, making it part of the broader rebuilding effort. The building was erected to serve the customs administration of the city's expanding port activities.

The interior customs hall displays maritime commerce symbols throughout its design, with a detailed checkerboard marble floor pattern that recalls the importance of harbor trade. This space shows how shipping and duty collection shaped daily life and activity in the building.

Access to the building is limited since federal agencies occupy most of the space, with public tours of the main hall available only by advance request. Plan ahead if you want to see the interior, as appointments need to be arranged beforehand.

The building preserves its original checkerboard marble flooring and classic staircase design exactly as completed in 1872. These original features offer a rare look at the craftsmanship and interior finishes typical of that building period.
