Having a structure that is fortified or protected by bastions, which are projecting parts of a fortification.

Bastioned → It is formed from "bastion" (from Old French *bastion*, meaning a projecting part of a fortification) and the suffix "-ed" (indicating a state or condition). The word "bastioned" refers to something that has been fortified or protected by a bastion.
Think of a 'bastion' as a protective structure, and when something is 'bastioned', it means it has been fortified or made secure.
