سنگر و استحکامات

What is a "bastion"?

A bastion is a projecting part of a fortification, typically a fortified structure or wall, designed to provide a defensive position for soldiers. It extends outward from the main walls of a castle or fort, allowing defenders to cover a larger area and fire upon attackers from multiple angles. The shape of a bastion is usually angular, which helps deflect incoming projectiles. Bastions often feature openings for cannons or other weapons, enhancing their defensive capabilities. This architectural element is commonly found in military structures from the Renaissance and early modern periods, where it played a crucial role in the defense strategy of fortifications, allowing for greater visibility and protection for defenders.
