Noun: Bastion is a technical term used in architecture and military engineering to denote a large, fortified structure that projects outwards from a defensive wall or rampart. These structures are typically pentagonal in shape and feature thick walls and gun emplacements, making them formidable defensive positions.
Verb: The verb “to bastion” refers to the act of fortifying a place with bastions. This process involves constructing these projecting defensive structures to enhance the overall strength and resilience of a fortification.
Example:
-
The defenders of the citadel valiantly held their ground against the onslaught, their resolve bolstered by the impregnable bastions that adorned its walls.
-
The architects of the city’s fortifications meticulously planned the placement and construction of bastions, ensuring that every strategic point was adequately defended.
