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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
