The Ford Building, at the south end of the Plaza de America, was considered by many to be the Exposition’s architectural wonder. Designed by Walter Dorwin Teague, the 90-foot tower was designed to look like a gearwheel laid on its side. One of the most popular buildings at the 1935 California-Pacific International Exposition, the Ford Building, once considered for demolition, is now the Aerospace Museum and listed on the National Register of Historic Places, and was the first Modernist resource designated by the City.
