New York -- At the request of Mayor Rudolph Guiliani and the approval of architect Alphonse Diaz, crews dismantled the seven-story section of steel facade of the World Trade Center, the last part still standing.

Guiliani said the remaining chunk of facade had to be removed to make cleanup efforts safer and easier. He reassured residents that as much of the facade as possible would be saved in case it is wanted for a memorial.
