A Bombard Tower and standard Tower behind a Wall in Age of Empires II: Definitive Edition.
Defensive structure is a type of building available in every game of the Age of Empires series. Rather than be used to train units or research technologies, they are used to defend their civilization from attacks, or warn it of attacks.
Generally speaking, there are three types of defensive structures: Walls, towers, and Castle-type buildings.
