Concentric Castles
What were Medieval Concentric Castles
A concentric castle was one of the most famous forms of a medieval castle.
It was the kind of castle that had two rings of outer walls with the inner wall usually higher than the outer one.
The inner wall was made higher so that it could be defended effectively from the outer wall.
Definition of a Medieval Concentric Castle
Contrary to what the term “concentric” might imply, the shape of concentric medieval castles was not circular but rectangular or sometimes irregular polygon.
Another feature distinguishing the concentric castles is that they generally did not have central free-standing keep.
History of Medieval Concentric Castles
The history of concentric castles could be tracked back to ancient times when Assyrians, Persians, and Egyptians built them.
In Europe, concentric castles became particularly popular during the high Middle Ages after the Crusades when rapid advancements were made in the siege technology.
Concentric medieval castles were also popular in medieval England during the reign of Edward I when huge such castles were built particularly in North-West Wales.
What were Medieval Concentric Castles made from
A variety of material was used in the construction of a medieval concentric castles.
The most important was of course stone which could be mined in quarries.
Stone in several of these medieval castles was also used from the ruins of old Roman fortifications.
Other materials that were commonly used in the construction of concentric castles included hard chalk, flint stone, sandstone, and limestone.
Lime mortar was used to keep the stones in place and consisted of a mixture of water, coal, and lime.
Medieval Concentric Castle Defenses
Since a concentric castle consisted of outer and inner walls, this kind of medieval castle provided a solid defense.
The inner wall could be defended form the outer wall and once the outer wall was penetrated by the enemy, the inner wall could still be used to protect the actual castle.
The rounded or polygonal shaped keeps were particularly important because they eliminated the risk of mining underneath the corners which was a huge advantage.
Another important factor for defense was the presence of multiple walls, with the inner most wall being the highest.
This allowed the defense of the medieval castle to be established on multiple levels at the same time, making it virtually impenetrable.
Medieval Concentric Castles walls
Medieval concentric castle walls were one feature that distinguished them from other forms of medieval castle.
The outer wall was called the “curtain wall” and contained projecting towers which served as the first line of defense in case of an attack.
The thickness of the curtain wall could be anywhere between 6 to 20 inches.
The inner walls of the medieval concentric castle were higher which allowed the defenders at those walls to observe the activity on the outer wall and plan the defense accordingly.
Concentric Castle Summary
Concentric castle was generally considered the most secure form of medieval castle due to its solid defense.
However, concentric castles had their weaknesses as well.
To begin with, massive resources were needed to build these castles.
They also required more workers and more time to be build and it was common for concentric castles to be built in several years.
With larger garrisons and more soldiers, prolonged sieges could sometimes result in starvation.
