The majority of the rooms, 68 in all, are on display at the Art Institute of Chicago, where they document European and American interiors from the late 13th century to the 1930s and the 17th century to the 1930s, respectively. The Art Institute's rooms were created by Thorne and her craftsmen between 1932 and 1940 at her studio on Oak Street on the city's Near North Side ; the 31 European rooms were finished by 1937, while the 37 American rooms were completed by 1940. The rooms were gifted to the museum in 1941, and put on permanent display in 1954. The Art Institute of Chicago's rooms are among the museum's most popular permanent collections.
