The Wanamaker Grand Court Organ, located in Philadelphia, Pennsylvania, is the largest fully functioning pipe organ in the world, based on the number of playing pipes, the number of ranks and its weight. The Wanamaker Organ is located within a spacious 7-story Grand Court at the John Wanamaker Store and was played twice a day Monday through Saturday. The organ was featured at several special concerts held throughout the year, including events featuring the Friends of the Wanamaker Organ Festival Chorus and Brass Ensemble.
