During WWI, areas of East Boston served as an internment camp for Germans taken off of ships. Period images show small unfenced buildings and tiny gardens built by the internees, leading right up to the water's edge. In 1919, moves were undertaken to formalize these facilities. Originally officials planned to use one of the Harbor Islands to replace their rented quarters on Long Wharf, but this plan was abandoned for a site on Marginal Street, directly on the East Boston wharves. Construction began in late 1919 on the East Boston Immigration Station, which served as Boston's first purpose-built immigration station. Unlike Ellis Island in New York, inspectors at the East Boston station processed immigrants at steamship docks, only transferring to the immigration station problem cases who had issues with their paperwork or required a secondary interview. Opposite the station, steps leading to East Boston were called the ‘Golden Stairs’ “because they represented the final climb to golden opportunity in America for countless Europeans." The station operated from 1920 to 1954 as the region’s immigration hub.
