The Museum of the American Diplomatic Mission is also called the Old Museum of the American Diplomatic Mission. It is a national historical monument on the territory of a foreign state - Morocco. The museum is located in an elegant Moorish type mansion with stucco molding, on the picturesque Rue d'Amerigue street, in the city of Tangier. The building for the museum was donated by the Sultan of Morocco Moulay Suleiman in 1821. The museum was later expanded and turned into a complex. The building was surrounded by a beautiful green courtyard. Then another building was added, which was used as a reception room, and over which three more floors were subsequently completed. In 1920, land and other buildings were bought across the road from the museum, and so the museum was significantly expanded. During World War II, the building served as the headquarters for scouts from the United States of America. Under the Consul General Maxwell Blake, the museum building had about 40 rooms. There is an observation deck on the roof of the museum’s central building, which offers scenic views of the Strait of Gibraltar and the local harbor. In the museum exposition you can see many paintings, more than 40 artists from 11 countries, many famous Moroccan rugs, cards, photographs, furniture and many other different exhibits. The museum currently has the Institute for Moroccan Studies and Arabic Studies, the Center for the Study of Moroccan-American Relations, the Cultural Center of the Kingdom of Morocco, and a scientific library. The Museum of the American Diplomatic Mission is a symbol of the Moroccan-American Friendship Treaty.
