The defining event of the weekend citywide: victims' families read all 2,983 names on the Memorial plaza in the morning and the plaza reopens to everyone that afternoon ahead of Tribute in Light.

Twenty-five years on, this is the day the city stops. Seven moments of silence begin at 8:46 AM as victims' families read all 2,983 names on the Memorial plaza, and when the plaza reopens to everyone at 3 PM you can pay respects at the twin reflecting pools before the Tribute in Light beams switch on at dusk. It is the defining event of the weekend — solemn, communal, and unrepeatable at this scale.

What to expect

The morning name-reading ceremony (8:30 AM to about 1 PM) is reserved for victims' family members, with a public livestream at 911memorial.org/live. Once the plaza reopens in the afternoon, anyone can visit the reflecting pools and bronze name parapets, with heavy crowds, flowers laid in the engraved names, and a strong security presence. From dusk on Sep 11 until dawn on Sep 12, the Tribute in Light beams are visible across the city.

Good to know

  • The morning ceremony is for victims' families only — the public watches via the livestream at 911memorial.org/live.
  • The Memorial plaza is closed to the public until the afternoon (it has reopened around 3 PM in past years); the Museum is reserved for family members all day.
  • Seven moments of silence are observed, the first at 8:46 AM — expect pauses and bell-ringing citywide.
  • Tribute in Light shines dusk-to-dawn; Brooklyn Heights Promenade and downtown waterfronts are classic vantage points, and a live broadcast airs at 8 PM ET.
  • Expect street closures and airport-style security around the World Trade Center site all day.
