Monday marks 16 years since the Sept. 11, 2001, terrorist attacks. Once again the iconic "Tribute in Light" in New York City is shining brightly into the night sky and will continue to do so all day.
Events were also held across Massachusetts in remembrance of the terror attacks.
At the State House, there was a flag lowering, moment of silence, and reading of names marking the hour the towers were attacked.
At 8:46 a.m., a moment of silence was held at Logan Airport to remember the passengers and crews of American Airlines Flight 11 and United Airlines Flight 175 - the two planes that departed Logan, but were hijacked and flown into the Towers.
At 1 p.m. a wreath laying ceremony was held at the Boston Public Garden.
"We come together today to honor those precious lives that were lost 16 years ago," Boston Mayor Marty Walsh said just before the wreath laying. "May we all know that no matter how many years go by or as long as we live, we will never ever forget."
A blood drive was also held from 7 a.m. to 2 p.m. at Fenway Park in honor of victims like Jeff Coombs, who was a passenger on Flight 11.
Rather than just grieving, Jeff's wife Christie spent the day watching, listening and helping with the healing.
"Acts of kindness. Service projects. Do something positive in their memory," Coombs said. "That's the best way to be remembered."
Representatives of Connecticut, New Hampshire, Maine, Vermont and Rhode Island also marked the anniversary of the Sept. 11 attacks Monday at ceremonies at police stations and fire houses, schools, and memorials.
New Hampshire Sen. Maggie Hassan attended the Manchester School District's remembrance ceremony Monday morning. She said she was grateful to be with the students "as we look toward the future with hope."
Maine Sen. Angus King said hope, love, and compassion rose above the fear and terror felt that day because the American spirit shone through.
Rhode Island Gov. Gina Raimondo honored the thousands of innocent victims who died on Sept. 11 and paid tribute to the heroism of the first responders. She said it was a time to reflect on the ways in which the nation came together after unimaginable tragedy.
Vermont Gov. Phil Scott asked people to remember those who were lost, but also how strong the country is when it joins together, united by the values they share as Americans.
