Smithsonian Arts and Industries Building, District of Columbia

Located next door to the Castle, the headquarters of the Smithsonian, the Arts and Industries Building was the first addition to what would become the continuously expanding Smithsonian. It is a Victorian exhibition hall that contains rotating exhibits on a wide range of subjects, and features a model train set circling a miniature Smithsonian Castle. When this building opened, in 1881, it was called the National Museum Building. It was renamed when the natural history displays were extracted, and moved across the Mall, in 1910, into the new National Museum of Natural History.
