St. Louis World's Fair

The St. Louis World's Fair, more properly known as the Louisiana Purchase Exposition, was designed to celebrate the centennial of the historic land acquisition in 1803. It was delayed a year to enable more international participation. An estimated 20 million people visited the Fair between April 30 and December 1, 1904.

See the Library of Congress' digitized map of the fair venue, which covered over 1200 acres, to pinpoint the locations of the views and buildings.  Another interactive map combines the original with current information (be advised that North is at the bottom).

The 212-page "Official Guide to the Louisiana Purchase Exposition" has also been digitized for online viewing and searching.
