The Bastille was a fortress in Paris, originally built in the late 14th century to defend the eastern approach to the city. Over time, it became a state prison used by the kings of France. It symbolized the tyranny of the monarchy, as many political prisoners were held there without trial. On July 14, 1789, the storming of the Bastille marked a pivotal moment in the French Revolution. This event represented the people's uprising against oppression and the fight for liberty. Today, July 14 is celebrated as Bastille Day, a national holiday in France, symbolizing freedom and democracy.
