The crew of the Coast Guard Cutter James Rankin set the historic Francis Scott Key buoy in the Patapsco River Monday near the Key Bridge.
The buoy marks the symbolic spot where the ship carrying Key, who wrote The Star-Spangled Banner, was anchored during the bombardment of Fort McHenry in 1814. Each year, the buoy is set in the spring to mark the historic location of the event, and is removed in the fall.
Besides being the battle that inspired Key to write the Star Spangled Banner, historians will tell you just what an important battle this was for the United States in the War of 1812.
