The National Museum of Korea is one of the most beautiful and largest museums in this part of Asia. The modern building was built for the museum for reopening in 2005. The building has three floors, and the settings are symbolically divided into a left side that represents the past, and a right side that represents the future. The first floor is the Prehistory and Ancient History Gallery, with about 4,500 objects, the second floor is the Donation Gallery and the Calligraphy and Painting Gallery with about 900 objects, while the third floor is the Sculpture and Crafts Gallery, with 630 objects and the Asian Arts Gallery with 970 objects. One of the main attractions is the 13,5-meter-high marble pagoda, which has ten floors and is located in the museum so it would be protected from the harmful effects of acid rain.
