Tribute in Light

In what has become one of the most moving — and visible — 9/11 memorials, two giant pillars of light near where the World Trade Center’s twin towers once stood were turned on in lower Manhattan this week to mark the 15th anniversary of the Sept. 11, 2001, terrorist attacks.

The Tribute in Light art installation consists of 88 searchlights that create two vertical columns of light.
