Underground fortifications

Definition

Underground fortifications are structures built below ground level designed to protect military personnel and equipment from enemy attacks and to serve as strategic defense points during conflicts. These fortifications became especially significant during wartime for providing shelter from bombings, ensuring supply storage, and maintaining operational command. In the context of warfare, their construction was often driven by the necessity to adapt to new military technologies and tactics that increased the destructiveness of aerial bombardments.
