The Marquette Building, also known as the Boatmen's Bank Building, is a historical building in downtown St. Louis. It was completed in 1914 at Broadway and Olive Streets, at 19 stories, designed by the St. Louis architecture partnership of Eames and Young. The building stands at 20 stories with a 2-story penthouse atop the 20th floor. A 1915 Annex, also designed by Eames and Young, was razed in 1998. The Marquette Building was added to the National Register of Historic Places the same year, and was redeveloped for condos in 2007. The building roof sports a small pool atop the eastern wing and a dog park/ relief area on the western wing, that are available to building residents.
