The event will begin at 10 a.m. on the Town Green in front of City Hall, 2342 Oak Road.
Mayor Kelly Kautz, who helped organize the event, said it is designed to let residents know about the importance of the flag.
“This is to celebrate our flag,” Kautz said. “It’s really to honor the flag and the values it stands for.”
The event will feature the Sons of the American Revolution firing muskets and soldiers from each American war and conflict since World War II.
Keynote speaker State Sen. Gloria Butler will talk about the history of the flag and the Snellville Police Department Honor Guard will be on hand.
There will also be patriotic music performed throughout the event.
