The National Museum of American History opened in 1964. In 1980, the museum was renamed the National Museum of American History to represent its mission of the collection, care, study, and interpretation of objects that reflect the experience of the American people. The museum is part of the Smithsonian Institution and located on the National Mall.
Each wing of the museum's three exhibition floors is anchored by a landmark object to highlight the theme of that wing. These include the John Bull locomotive, the Greensboro, North Carolina lunch counter, and a one of a kind draft wheel. Landmarks from pre-existing exhibits include the 1865 Vassar Telescope, a George Washington Statue, a Red Cross ambulance, and a car from Disneyland's Dumbo Flying Elephant ride.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
