The Wanamaker Organ, located in Philadelphia, Pennsylvania, is the largest operational pipe organ in the world, located within a spacious 7-story court in a Macy's department store. It is played twice a day, Monday through Saturday, and much more often during the Christmas season. The organ is also featured at several concerts held throughout the year, often with a small brass ensemble, string ensemble, or even the Philadelphia Orchestra.
