Foundation Hall is a room of massive scale and soaring height. Here, the slurry wall, a surviving retaining wall of the original World Trade Center that withstood the devastation of 9/11, is presented as a testament to survival and determination. Against this backdrop the Last Column stands 36-feet high and is covered with mementos, memorial inscriptions, and missing posters placed there by ironworkers, rescue workers and others. Removed during a ceremony to mark the close of the recovery effort at Ground Zero, the column, laid prone, was draped with an American flag and escorted by honor guard. Standing tall once again, the Last Column encourages reflection on the foundations of resilience, hope, and community with which we might build our collective future.
