ST. LOUIS, MO (KTVI) – Monday, March 10 is the anniversary of when the American flag was raised over St. Louis for the first time in 1804 taking the place of the French flag.
Christopher Gordon, from the Missouri History Museum, explained the three-day process to John Pertzborn.
In 1804, Upper Louisiana was transferred from Spain to France. The French flag flew over St. Louis for 24 hours before the US flag was raisedand the United States took formal possession.
The inhabitants of the village of St. Louis were ordered to assemble at the commandant's headquarters on Main Street. They watched as the Spanish flag was lowered, the French flag was raised and lowered, and then the US flag was raised.
