Fortified buildings are structures designed to withstand attacks or natural disasters. They often feature thick walls, reinforced doors, and strategic positioning to enhance security. Common examples include castles and military bunkers, which were built to protect inhabitants from enemies. These buildings may also incorporate modern technology, such as surveillance systems and reinforced glass, to improve safety. Fortified buildings can be found in various locations, from urban areas to remote landscapes, serving both historical and contemporary purposes in defense and protection.
