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:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
