defensive structure
Wall or rampart
A defensive structure is any construction designed to protect against attack—walls, fortifications, bunkers, trenches, or barriers.
The term appears in military history and strategy: The castle's defensive structures withstood the siege.
It extends to any physical barrier meant to repel or slow an enemy: They built defensive structures along the border.
