A large number of Impressionist paintings have made the Art Museum of Chicago the second-ranked art museum in the United States, focusing on art from Greece, Rome, Europe, and the United States, and combining Asian and African art. The Chicago Art Museum is located in the heart of downtown Chicago, a few steps from Millennium Park. Tickets are 25 for adults and can be rented a Chinese-language guide, although the introduction of many famous paintings in the museum is still in English. The museum is made up of three three-storey buildings. The exterior is Victorian and there are two huge bronze lions in front of the door, including the railway. Collection exhibits are extremely rich, mainly painting and sculpture. The time span is from ancient pottery of ancient Egypt in 3000 BC to contemporary pop art, including good Chinese bronzes, Monet and Van Gogh's oil paintings. This state-of-the-art art museum is known for its collection of Impressionist and Post-Impressionist masters and American art, such as Monet, Van Gogh, Picasso, Renault and more than 350 masterpieces. It is also one of the top three surrealist collections in the United States. Along the grand staircase you can admire the exquisite pieces of the ruined historic Chicago landmark. However, the Chicago Museum of Art's overall collection is a bit less than the Metropolitan Museum, the Boston Museum of Art, and the National Gallery of Washington.
