New York City is preparing to honor the memories of those lost and acknowledge the resilience shown in the aftermath of the September 11, 2001, terror attacks with dozens of events planned throughout the week.

This year marks the 25th anniversary of the attacks that claimed the lives of 2,977 civilians and first responders at Ground Zero, with hundreds more having since died from illnesses and injuries linked to the tragedy.

Commemorative Ceremonies

The annual ceremony at the 9/11 Memorial and Museum will begin Friday morning at 8:40 a.m. This year's observance will include a seventh moment of silence to specifically honor those who have died from 9/11-related illnesses, a first for the ceremony. The event will also feature the reading of names of victims from both the 2001 attacks and the 1993 World Trade Center bombing by their loved ones. The ceremony will be livestreamed.

Earlier in the week, the NYPD Detectives’ Endowment Association is scheduled to host a wreath-laying ceremony at Ground Zero on Tuesday. The 11:45 a.m. event will honor NYPD Detective Joseph V. Vigiano and FDNY Firefighter John Vigiano, brothers who died trying to save lives, along with NYPD Detective Claude “Dan” Richards. The ceremony will also pay tribute to the 79 NYPD detectives who later succumbed to illnesses connected to their work following the attacks.

On Wednesday, the NYPD will dedicate a new remembrance wall at One Police Plaza to honor first responders killed in the attacks and those who have since died from related illnesses. The wall will recognize nearly 500 individuals.

Remembrance and Resilience Events

The American Council of Engineering Companies of New York is hosting “Engineering Resilience: 25 Years of Rebuilding, Remembrance and Renewal” on Thursday. This event will feature discussions on the response to structural conditions after the attacks, investigations, and updates to building codes and downtown redevelopment.

A group of over 200 cyclists, including firefighters who responded on 9/11, will conclude their 343-mile “Ride for Resilience” journey at the World Trade Center on Thursday. The ride, which began in Boston, honors those lost and those living with 9/11-related illnesses. An arrival ceremony with a moment of silence at the 9/11 Memorial and a 2 p.m. ceremony at Battery Park are planned.

St. Patrick’s Cathedral will host a special Mass on Thursday at 5 p.m., with Archbishop Ronald Hicks inviting bishops from across New York State. The Mass will be livestreamed, and a second ceremony is scheduled for Friday afternoon.

The “Steel Across America Tour,” which has traveled over 10,500 miles, will conclude Friday at the World Trade Center with the return of a massive piece of steel recovered from Ground Zero. The family of FDNY hero Stephen Siller will retrace his final journey through the Brooklyn-Battery Tunnel.

Artistic and Cultural Tributes

The annual “Tribute in Light” will illuminate the New York City skyline from sunset on Friday until dawn on Saturday, shining from the site where the Twin Towers once stood. The Memorial Plaza will be open to the public starting at 3 p.m. This year, the Tribute in Light will be aired nationally on Disney-affiliated channels and streamers.

Sporting and Musical Events

The Subway Series will feature a game between the Mets and Yankees on Friday at 6:30 p.m. in the Bronx, with a pre-game ceremony to honor the 25th anniversary and first responders.

On Saturday, the NYPD Pipes and Drums will perform at Madison Square Garden’s Infosys Theater for “A Night of Remembrance – 25th Anniversary 9/11 Memorial Concert,” featuring guest bands and Irish tenor Dr. Ronan Tynan.

Museum Exhibition

Opening Saturday, the 9/11 Memorial & Museum will unveil a new special exhibition, “In Their Honor: 25 Years of 9/11-Inspired Service.” The exhibit explores how grief was transformed into action and service in the wake of the tragedy.
