Hotel de Inmigrantes is a complex of buildings, often compared to a citadel, constructed between 1905 and 1911 in Buenos Aires, Argentina to receive immigrants and stem the tide of communicable diseases following mass cholera outbreaks across the globe. The hotel, which saw more than a million immigrants pass through during its 42 years, now houses the National Museum of Immigration as well as the National University of Tres de Febrero's Contemporary Art Center.

The Port of Buenos Aires is the principal maritime port in Argentina. Operated by the Administración General de Puertos, a state enterprise, it is the leading transshipment point for the foreign trade of Argentina.
