The Jamestown Exposition was one of the many world's fairs and expositions that were popular in the United States in the early part of the 20th century. Commemorating the 300th anniversary of the founding of Jamestown in the Virginia Colony, it was held from April 26 to December 1, 1907, at Sewell's Point on Hampton Roads, in Norfolk, Virginia. It celebrated the first permanent English settlement in the present United States. In 1975 the 20 remaining exposition buildings were included on the National Register of Historic Places as a national historic district.
