The Wanamaker Building was built on the original site of the Grand Depot at Thirteenth and Market Streets to house the flagship Wanamaker Department Store and its corporate offices. Since then the property has transitioned from a landmark department store headquarters to a major Class AA office and retail property with twelve (12) stories above ground and three (3) stories below. One of the largest buildings in Philadelphia, the property occupies an entire city block bounded by Market Street, Chestnut Street, Thirteenth Street and Juniper Street
