World's Fair Pavilion

World's Fair Pavilion is a Mission Revival-style open-air shelter perched atop Government Hill in Forest Park, St. Louis. Built in 1909 with proceeds from the 1904 Louisiana Purchase Exposition, the pavilion overlooks a fountain and reflecting pool added in 1930 — a setting that has drawn receptions, company picnics, benefits, and special events for over a century. The covered pavilion floor spans 109 feet by 51 feet and accommodates approximately 500 seated guests. North and south patio areas extend the event footprint on either side of the building, while a catering area at the west end provides water access and electrical service. Accessible restrooms are available on-site, and 15 trash receptacles are included with rental. After significant deterioration, Forest Park Forever raised $1.1 million to fully restore the structure in 1998, returning it to its original architectural character. The pavilion is available by permit through the City of St. Louis Parks Department, with reservations handled in person up to 18 months in advance.
