Fortress

A fortress is a strong, fortified structure built to defend against attack or invasion. It typically features thick walls, battlements, and strategic positioning to withstand enemies and protect inhabitants. Historically, fortresses served as military strongholds, administrative centers, or refuges during conflicts. Modern equivalents include military bases and secure installations that prioritize safety and defense. The key purpose of a fortress is to provide a secure environment by using design and construction techniques that resist outside threats and ensure the safety of those inside.
