Opened on September 1, 1894, St. Louis Union Station was the world's largest and busiest passenger rail terminal, designed by architect Theodore Link in the Romanesque Revival style with a signature 230-foot clock tower. The station served 22 railroads at its peak and expanded in 1904 to welcome millions of visitors to the St. Louis World's Fair. Designated a National Historic Landmark in 1970, the complex underwent a $150 million restoration — described as the largest adaptive reuse project in the country at the time — before reopening in 1985. Today the property operates as a full-service hotel and event destination in downtown St. Louis. The event facilities encompass more than 100,000 square feet, anchored by The Midway, a 43,000-square-foot hall beneath a steel-trussed glass roof that fills the space with natural light for gatherings ranging from intimate weddings to large-scale trade shows. The Grand Hall, rising 65 feet at its tallest point, features sweeping archways, fresco and gold leaf detailing, mosaics, and art glass windows from the station's original 1894 construction. Four ballrooms provide additional settings for weddings, galas, and private celebrations.
