The Memorial Fence: A ten foot tall (3.05 m) chain link fence was originally installed around the area that is now the Reflecting Pool and the Field of Empty Chairs to protect the site from damage and visitors from injury. The Fence stood for more than four years and became famous itself, with visitors leaving stuffed animals, poems, keychains, and other items there as tributes. During the construction of the Outdoor Memorial, 210 feet (64 m) of the Fence was moved to the west side of the Memorial, along the 9:03 side or the 'healing' side. The remainder of the Fence is in storage. Visitors may still leave small items along and in the Fence; the mementos are periodically collected, catalogued, and stored.
