Visit to Detroit, Michigan on May 27, 2013 with my flickr contacts Granttt73 and ROGERIOMACHADO. Detroit's Guardian Building is one of the most flamboyant architectural landmarks in the city. Designed by Wirt Rowland in Mayan Revival and Art Deco styles, the building opened in 1929 by the Union Trust Company, who nicknamed it the Cathedral of Finance. Having undergone a recent renovation, the building is a National Historic Landmark. Some interesting links: Guardian Building history, Wikipedia Guardian Building Historic Detroit Guardian Building
