Etymology

Origin of bastion

1590–1600; < Middle French < Italian bastione, equivalent to Upper Italian bastí ( a ) bastion, originally, fortified, built (cognate with Italian bastita, past participle of bastire to build < Germanic; see baste 1) + -one augmentative suffix


Explanation

When the battle is getting long and the odds are getting longer, retreat to your bastion to regroup and prepare for the next round of fighting. A bastion is a stronghold or fortification that remains intact. French Independence Day, or Bastille Day (July 14), commemorates the storming in 1789 of the French king's prison/fort, the Bastille. Bastion and Bastille share the root bast, which means "build." Bastion can refer to any place to which one turns for safety; that can include not only buildings but also concepts, ideas, and even beliefs. The Church, for example, is a bastion of many religious beliefs.
