fortress

Definition

A heavily fortified stronghold designed to withstand prolonged attacks, essentially a castle on steroids. These massive defensive structures represent the pinnacle of military architecture, combining walls, towers, and strategic positioning. If a fort is a secure house, a fortress is a secure mansion with a moat and very unfriendly neighbors.

Example Usage

The medieval fortress had walls twenty feet thick and was considered impregnable.
