The Bastille, French for "castle", was a prison located in Paris, used by the King of France.
It was best known as a symbol of the French Revolution, when French commoners stormed the Bastille as their first action against the King and Queen.
The Tenth Doctor said that the "Storming of the Bastille" was not as glamorous as the French would have us believe, saying that it was more of a "light drizzle". (PROSE: Forever Autumn)
In an alternate Paris, a futuristic New Bastille was constructed. (PROSE: The Man in the Velvet Mask)
