Cute Young Brunette Girl Posing At The Bastion Wall

• A cut bastion is that which has a re-entering angle at the point. It was sometimes also called bastion with a tenaille. Such bastions were used, when without such a structure, the angle would be too acute. The term cut bastion is also used for one that is cut off from the place by some ditch. These are also called Hersee's after their creator, Andrew Hersee.
• A composed bastion is when the two sides of the interior polygon are very unequal, which also makes the gorges unequal.
• A regular bastion is that which has proportionate faces, flanks, and gorges.
• A deformed or irregular bastion is one which lacks one of its demi-gorges; one side of the interior polygon being too short.
