The Nationality Rooms are a group of 31 classrooms in the University of Pittsburgh's Cathedral of Learning depicting and donated by the national and ethnic groups that helped build the city of Pittsburgh. The rooms are designated as a Pittsburgh History and Landmarks Foundation historical landmark and are located on the 1st and 3rd floors of the Cathedral of Learning, itself a national historic landmark, on the University of Pittsburgh's main campus in the Oakland neighborhood of Pittsburgh, Pennsylvania, United States. Although of museum caliber, 29 of the 31 rooms are used as daily classrooms by University of Pittsburgh faculty and students, while the other two are display rooms viewed through glass doors, utilized primarily for special events, and can only be explored via special guided tour. The Nationality Rooms also serve in a vigorous program of intercultural involvement and exchange in which the original organizing committees for the rooms remain as participants and which includes a program of annual student scholarship to facilitate study abroad. In addition, the Nationality Rooms inspire lectures, seminars, concerts exhibitions, and social events which focus on the various heritages and traditions of the nations represented. The national, traditional, and religious holidays of the nations represented are celebrated on campus and the rooms are appropriately decorated to reflect these occasions. The Nationality Rooms are available daily for public tours as long as the particular room is not being used for a class or other university function.
