Types of Castle Siege Weapons

Various types of castle siege weapons were developed over the centuries. Advanced engineering techniques were used in some of them while others were relatively simple.

Some of the most popular castle siege weapons used during the medieval times included the Ballista, Mangonel, battering rams, catapults, siege towers, and Trebuchets.

Ballista – Castle Siege Weapon

The Ballista was one of the most important castle siege weapons whose shape was similar to that of a large crossbow. It worked on the same principle that a dart-throwing machine works, only on a much larger scale.

Heavy bolts, darts, and pieces of iron could be aimed at the castle with a Ballista. It was used in the ancient world as well but became widely popular during the medieval times.

Mangonel – Castle Siege Weapon

The Mangonel was another popular castle siege weapon which was quite similar to a catapult and was used to fire heavy projectiles from a large bucket attached to it.

It had an advantage over other catapults that its design was simpler and thus it could be constructed easily. However, the Mangonel was not as accurate in hitting it’s target as a Ballista. Just like a Ballista, it was used in the ancient world but became more famous during medieval times.

Battering Ram – Castle Siege Weapons

Among the most common form of castle siege weapons were battering rams which could be made into various sizes and shapes. For instance, there were simple log battering rams, battering rams with flat heads, battering rams with iron or bronze heads, battering rams with actual ram’s style head, and others.

Sometimes a roof was used on the battering ram in order to protect the soldiers from incoming enemy missiles. This roof was called a penthouse. Use of battering rams was quite popular because they were very simple to construct and easy to operate. However, they could only be used once the castle gate had been approached.

Other Kinds of Castle Siege Weapons

Various other kinds of castle siege weapons were also prevalent during the medieval times. For instance, there was a Trebuchet which was not very different from a catapult.

It was mainly used to throw heavy stones and rocks at the castle gate and walls to demolish them. Similarly, another castle siege weapon was called a siege tower which was mainly constructed to protect soldiers and ladders while approaching the castle walls.

Castle Siege Weapons Summary

Castle siege weapons played a very important role in conquering a medieval castle. Without these weapons, it was almost unthinkable to defeat the army within the castle.

Thus, over the centuries, various new castle siege weapons were constructed with sophisticated techniques, although many of these castle siege weapons were also prevalent in the ancient times. Their use, however, became particularly widespread during the medieval times when large number of castles was built.
