Starting March 11, 2002, eighty-eight searchlights were installed and arranged to form two beams of light shooting straight up into the sky. This was called the "Tribute in Light", and was originally lit every day at dusk until April 14, 2002. After that, the lights were lit on the second anniversary of the attack and have been lit on each subsequent September 11 since then. In February 2005, the New York City Medical Examiner's office ended its process of identifying human remains at the site.
