The center's original buildings were the United States Science Pavilion designed by Minoru Yamasaki for the 1962 World's Fair in Seattle. Eventually becoming Pacific Science Center, the World of Science, along with the Worlds of Art, Entertainment, Commerce and Industry, and Tomorrow were the five main theme areas that were intended for the masses at the World's Fair. Located at the southernmost end of the fairgrounds and west of the Space Needle, the World of Science was located under the arches, an easily identifiable landmark.
