Answer 1

The medieval armory, fortress, and political prison known as the Bastille represented royal authority in the centre of Paris.

The prison contained seven inmates at the time of its storming. The act was seen, by the revolutionaries, as a symbol of the monarchy's abuses of power; its fall was the flashpoint of the French Revolution.

In France, Le quatorze juillet (14 July) is a public holiday, usually called Bastille Day in English.
