The Rookery Building is one of the most esteemed buildings in Chicago, in terms of architectural merits. Completed in part by legendary architect Daniel Burnham in 1888, it is considered one of his masterpieces, and was once the location of the office he shared with business partner John Wellborn Root. At twelve stories tall, it is considered one of the oldest standing high-rises in the city. The lobby was remodeled in 1905 by equally acclaimed architect Frank Lloyd Wright. The Rookery was designated a Chicago Landmark in 1972 and was added to the National Register of Historic Places in 1970. The Rookery hosts periodic public tours and is available for private events.
