The enormous instrument — 28,750 pipes, 287 tons and snaked throughout the building — isn’t going anywhere. But Macy’s is, closing its showpiece store at 13th and Market Streets for good Sunday.

Built in 1904 for the St. Louis World Fair, The Wanamaker Organ is a National Historic Landmark. Considered the largest fully-functioning organ in the world, it’s composed of more than 28,000 pipes, which are stored in various parts of the building.

Many people flocked to the Center City Macy's Saturday to say goodbye and hear the sounds of the famous Wanamaker Organ.
