Pueblo Union Depot, constructed between 1889 and 1890, is a historic railroad station in Pueblo, Colorado. Designed in the Richardsonian Romanesque style by the architectural firm Sprague & Newell, it originally served multiple railroads, including the Denver & Rio Grande Western Railroad and the Atchison, Topeka and Santa Fe Railway. Today, the depot is a prominent event venue, hosting weddings, corporate gatherings, and community events, while also housing the Pueblo Railway Museum.
