Определение и Значение "embrasure"

What is an "embrasure"?

An embrasure is an opening in a fortified wall or parapet that allows for the placement of weapons, such as cannons or rifles, while providing protection for the defenders. This design typically features a wider opening on the outside and a narrower opening on the inside, allowing soldiers to fire at attackers while remaining shielded from enemy fire. Embrasures are commonly found in fortifications, castles, and military structures, enhancing the defensive capabilities by enabling effective firing angles while minimizing exposure. This architectural feature is essential for maintaining security during battles and sieges, contributing to the overall strength of the fortification.
