The Tribute of Light in Manhattan is one of several September 11 ceremonies held in New York City.

New York City has the Ground Zero ceremony, but there are traditions from coast-to-coast. Today is the 25th anniversary of September 11, 2001, when terrorists hijacked four commercial passenger planes, crashing two into New York's Twin Towers and killing 2,977 people. Another plane hit the Pentagon in Arlington County, Virginia, and the fourth plane crashed into a field in Shanksville, Pennsylvania, after the passengers on board attempted to retake the cockpit and overcome the hijackers. Since the attacks, the US has created over 1,100 memorials across all 50 states where visitors can reflect and honor those who died. Communities have also developed traditions and ceremonies to mark the anniversary. Visitor numbers can vary depending on how the community is connected to the attacks. From stair climbs and gun salutes to walks of remembrance and observances, here are ways US cities have commemorated the attacks.

Twenty-three New York Police Department members died in the line of duty, and hundreds of NYPD officers have died as a result of 9/11-related illnesses. The 9/11 Memorial & Museum, located at the World Trade Center in Lower Manhattan, is the heart of the nation's 9/11 ceremonies. During each anniversary, the plaza holds a ceremony for the families of victims at the Memorial Plaza to read aloud the names of those killed. The ceremony holds seven moments of silence to mark the times when each of the World Trade Center towers was struck, when each tower fell, the Pentagon attack, the United Airlines Flight 93 crash, and those lost to 9/11 health effects. The Museum also holds the "Tribute in Light," an annual public art installation located six blocks south of the World Trade Center. The installation shoots two beams of light — representing the Twin Towers — four miles up into the sky from dusk to dawn on the night of September 11. Among the various memorials located throughout the city, the New York City Fire Department holds an annual "Walk of Remembrance" earlier in September to honor Father Mychal Judge, a FDNY Chaplain who was killed while ministering to firefighters during the attacks.

The Pentagon has historically displayed an American flag from the building's roof near the impact zone. President Donald Trump attended the annual 9/11 ceremony at the Pentagon and delivered remarks. Vice President JD Vance attended the New York City ceremony alongside the four living former presidents, Bill Clinton, George W. Bush, Barack Obama, and Joe Biden. Arlington County will also commemorate the anniversary at Fire Station 5, with remarks from elected officials, a wreath-laying, and a rose-laying ceremony. More than 200 first responders, many of whom responded on the day of the attacks, will attend.

The stair climb at Colorado's famous Red Rocks Park and Amphitheater is one of the country's largest 9/11 Memorial Stair Climbs. The Denver Gazette reported the climb raised about $110,000 for two charities last year, including the FDNY Counseling Services Unit and the National Fallen Firefighters Foundation. About $1.4 million was raised nationwide for first respon
