The Palais de la Porte Dorée is a Paris museum located in the 12th arrondissement of Paris, between the Bois de Vincennes and the Porte Dorée. The palace houses two major centers: the National Museum of the History of Immigration and the Aquarium Tropical. The building that houses them is an "art deco" style building, built on the occasion of the 1931 Paris Colonial Exposition. The building was built to celebrate the colonial successes of France. First, in 1931, it was inaugurated as a "museum of the colonies". Later it changed its name several times: first in "Museum of the Colonies and of Foreign France", then in "Museum of overseas France". In 1960 it became the "National Museum of the Arts of Africa and Oceania", and only in 2007 the name was changed to the current one. The National Museum of the History of Immigration is a museum that documents the controversial problem of immigration in France, also making it clear the important role that immigrants have played in the construction and economic, cultural and social development of the country. The museum collects and preserves documentary material concerning the history of immigration, making it accessible to as many people as possible, to raise awareness of the challenges faced by those who transformed France into the multicultural country it is today. The collection therefore consists of testimonies, archival documents, photographs and works of art. As for the Aquarium Tropical, it is the most important aquarium in the French capital, whose purpose was to show the aquatic riches of the colonies to the general public. Even today it is possible to see many marine species from all over the world. The Palais de la Porte Dorée hosts many temporary exhibitions.
