The fort's superintendent said in the release, "It was breathtaking to witness these students and their teachers become part of history of Fort McHenry while learning about two of our nation's greatest symbols of freedom and democracy - the American Flag and the National Anthem."
So why did Fort McHenry specifically want to create the largest living American flag?
It seems like quite a few of the students who participated are really into the history of the whole thing. One was even hoping to see a re-enactment of the battle, telling The Baltimore Sun,"I thought the British were going to attack us."
Fort McHenry isn't alone in its national anthem celebrations this week.
A six-day festival is currently taking place in Baltimore. It's complete with musical acts, fireworks and live history demonstrations.
And University of Maryland's football team is wearing special jerseys in honor of the anniversary. Lyrics from the anthem are featured on both the jerseys and the players' helmets.
Fort McHenry isn't done celebrating yet, though. It has a week of activities planned - and it's also displaying the American flag that was recovered from the ruins of the World Trade Center after the 9/11 attacks.

Several hundred thousand people demanding an independent Catalonia have joined hands in an attempt to form a 400-kilometer (250-mile) human chain across the northeastern region of Spain. The demonstration Wednesday aimed to illustrate local support for political efforts to break away from Spain. Organizers estimated about 400,000 people took part in the human chain.

People hold placards with the colours of the Catalan flag as they take part in a demonstration in support of a Catalan vote on independence from Spain, in the northern Spanish Basque city of Bilbao on September 9, 2014, ahead of the Diada. The Diada marks what many in this northeastern region see as the day they lost their autonomy: September 11, 1714, when Barcelona fell to Spanish and French forces in the War of Succession that redrew the map of Spain. This year the Diada opens the final straight in the dash to hold a vote on whether Catalonia should break away from Spain -- a move the Spanish government has branded unconstitutional.
