DALLAS - There were a number of commemorations held across North Texas to honor the victims of the 9/11 attacks and first responders.

The city of Grapevine held its annual 9/11 Day of Remembrance Ceremony at the 9/11 Flight Crew Memorial.

Hundreds of first responders across Texas gathered in Dallas on Saturday to honor the victims of the 9/11 attacks.
The city hosted the 11th annual 9/11 Memorial Stair Climb at Fountain Place Tower in Downtown Dallas.
In full gear, firefighters, police officers, and emergency medical services personnel climbed 110 stories.
The stair climb symbolizes the trek to the top of the former World Trade Center towers in New York.
Each carried a picture of a first responder who lost their life 21 years ago.
"When I think about what they experienced that day, it makes climbing these stairs much easier," Plano Fire-Rescue Captain John Barrett said. "We have 110 floors. They didn’t make it to the top of the buildings that day. What they saw gives us inspiration to make this climb easy."
This year, money raised from the event will go to the Texas Line of Duty Death Task Force.
The non-profit helps critically injured first responders, families, and agencies of those who have died in the line of duty.
