CHARLESTON, S.C. (WCIV) -- The country's oldest museum celebrated one of the nation's most treasured songs on Saturday.
The Charleston Museum opened its courtyard to ring in the 200th anniversary of the Star-Spangled Banner with a nationwide singing event.
Millions of Americans performed the national anthem simultaneously at 4 p.m. Saturday.
The event was the largest worldwide singing of the anthem in history and was led by the Smithsonian in Washington, D.C.
The singers in Charleston and across the country were connected to the Smithsonian through a webcast.
It was the perfect event for Flag Day.
Across the Ravenel Bridge, the Knights of Columbus held a ceremony on the flight deck of the U.S.S. Yorktown. The event included local Boy Scouts and a reading of a proclamation recognizing the 60th anniversary of the addition of "under God" to the pledge of allegiance.
"The Knights several years ago decided to conduct ceremonies like we did today where we go to raise the flag and have a formal ceremony like that. We were blessed today on the Yorktown to have a bunch of Boy Scouts and Cub Scouts who spent the night and participated with us as well, so hopefully we are instilling the ideas of patriotism and our flag and certainly honor our God," said Neil Whitman with the Knights of Columbus.
June 14 was first recognized as national Flag Day in 1916.
