Probably my favorite building in Portland, Maine is the former Custom House building, an imposing granite building located a stone’s throw from the Portland Harbor. It was built to accommodate the city’s growing customs business, which, by 1866, was collecting $900,000 annually in customs duties—making Portland one of the most significant seaports in the country. The building is typical of the notable designs completed under the direction of Alfred B. Mullett, Supervising Architect of the Treasury from 1865 to 1874. Constructed between 1867 and 1872 (due to delays in obtaining granite for the upper stories) the U.S. Custom House combines elements of the Second Empire and Renaissance Revival styles and is one of the best preserved custom houses in New England. The interior custom hall is especially remarkable.
