The memorial searchlights have already begun shining at Ground Zero, as the 18th anniversary of 9/11 approaches. On the Upper West Side, two special events will allow people to commemorate and mourn the day. September 11 is on Wednesday.

Lincoln Center will once again host the Buglisi Dance Theatre’s Table of Silence project in the central plaza from 8:15 to 8:46 a.m. on the 11th. The dance performance involves more than 150 dancers and often draws a large crowd.

From 7 a.m. until 7 p.m., the Cathedral of St. John the Divine at 112th and Amsterdam will be showing a time-lapse video by artist Wolfgang Staehle, who had focused his camera on downtown New York on 9/11 intending “to convey the predictable normalcy of life at the start of the 21st century,” the cathedral said in a release. “With the 9/11 attacks, these mundane rhythms were ruptured as Staehle’s cameras chronicled the transformation of a routine workday into a city under siege.” He was also making similar time-lapse videos in Europe for a film called 2001.
