Once covering more than a block, today the Anheuser-Busch Office Building is the only remaining structure of what was the original Krug Brewery, the largest brewery among Omaha's original "Big 4" brewers. Anheuser-Busch took over the facilities after buying Krug.(2003) Building for the Ages: Omaha's architectural landmarks. Landmarks, Inc. p 63. The office building is one of the most elaborate examples of the Romanesque Revival style in Omaha. The Depot once included a stable, beer vault/ice house, famous gold basement and cobblestone alley.
