The 2002 World Monuments Watch List of 100 Most Endangered Sites was launched on October 11, 2001 by WMF President Bonnie Burnham at a press conference at the Museum of Modern Art in New York. The Watch List was expanded to 101 in the wake of the devastating destruction of the World Trade Center on September 11, 2001. Its vicinity—the Lower Manhattan area, was added as an imperiled urban site.
