The University of Pittsburgh Nationality Rooms were designed to represent and celebrate the cultures of various ethnic groups that settled in Allegheny County. The thirty-one Nationality Rooms located on the first and third floors of the Cathedral of Learning are a community space where visitors are invited to experience the rich heritage of the communities who inspired and supported their creation.

The rooms are also in use as university classrooms, giving students the opportunity to engage in learning in a unique setting that helps them to explore the historic diversity of the Pittsburgh region.
