Defensive fortifications

Defensive fortifications are structures built to protect people or territory from attack. These can include walls, bunkers, trenches, and movable barriers designed to delay, block, or withstand enemies' advances. They are strategically placed to defend important areas, such as cities, military positions, or borders. Fortifications can vary from ancient stone walls to modern reinforced structures, often incorporating features like towers or hidden traps. The goal is to provide a strong defense line that enhances safety, allows defenders to organize their response, and deters potential attackers.
