In honor of the World Trade Center towers collapse on 9/11, a ceremony will take place this Sunday.

Many law enforcement officials will climb the stairwells of the Hilton San Diego Bayfront Hotel to remember all of those who lost lives on the day of the tragedy. Those loosing lives included 343 firefighters.

According to the CBS 8 news-station, “The 9/11 Memorial Stair Climb, which begins just after 8 a.m., will raise money for programs that help injured firefighters and their families. Lt. Joe Torrillo, a retired Fire Department of New York firefighter who was trapped in the rubble of the World Trade Center and survived, is scheduled to speak about his experiences.”

All of those who participate in the Sunday morning events will receive a badge and a photo of someone who lost their lives fighting on September 11 in 2001, CBS 8 also said.

Many other events like this are taking place throughout the country. Today in Sacramento, firefighters climbed the Renaissance Tower in honor of those who served and lost lives on 9/11. Since the tower is only 28 stories, those climbing went up and down the staircases 4 times in order to climb 110 floors, in which the World Trade Center had.

The local CBS Sacramento news-station, said that each one person who climbed the tower attached to their coat, a photo of a firefighter, police officer or other official who served on 9/11.
