Learning Goal: to find out about attacking and defending a castle
1066–1500
Why castles?
When William invaded England he did not have many troops so he needed a way of making sure they were used effectively. This led to the rise of the castle.
The castles dominated the landscape. Because they were carefully located, any rebellion had to be made against a castle.
The motte and bailey castle design that William first used was good as a start but not as effective in the long term.
Defending a castle
This is because castles needed to be strong enough to survive an attack by any means.

The castle entrance
The castle entrance often had a barbican attached. This extra gatehouse protected the weakest part of the castle. There would be extra soldiers, and several heavy oak doors and portcullises to get past.

Defences before and at the main entrance
Why do you think the main entrance had so much defence?
Click on the murder holes, portcullis and drawbridge.
The castle battlements jutted out from the top of the wall so that soldiers could drop heavy stones and pour boiling tar onto the enemy below.
At the bottom of the curtain wall the walls were angled so that when stones were dropped they would bounce off the bottom and hit the attackers.
Castle defences
Castles were often built near rivers.
Why do you think this was?
There were a number of features which could be added to the castle to make it stronger. Most castles had round towers in their walls. This was so soldiers could fire in all directions along the front walls.
The strongest building was the keep. It had numerous defensive features including very thick walls, narrow staircases, big cellars for sieges. Even the entrance was raised and had drawbridges to stop an attack.
As castles were frequently under attack, they had to be as strong as possible.
Why did castles develop?
As the attackers improved their methods of attack, so the castle builders had to improve the castle’s ability to defend.
How do you think a battering ram was used to attack a castle?
Castle attack
In this picture the attackers are tunnelling. They would mine underneath the castle hoping to collapse it!
What are the advantages of this method of attack?
How would this catapult have worked?
Do you think it would have been very effective? Why?
These siege towers had a drawbridge at the top. The soldiers would climb up the tower and rush across the drawbridge onto the castle hoarding (the bit jutting out at the top of the castle). They were often covered in animal skins to provide further protection from arrows.
What do you think were the main disadvantages with this method of attack?
Which of the methods of attack do you think would have been the most effective? Why?
Can you suggest any other methods attackers might have used?
Castles were sometimes so strong that the only method of attack was to wait. This was called laying siege. It was basically staying out of arrow range and surrounding the castle until it was starved into submission.
Sieges could take a very long time to work. Many castles had wells in the keep and large storerooms always prepared in case of a siege. The best time to attack would be spring as all the winter food would be used up by then and the defenders would have little supplies to last on.
Siege
Sometimes attacking a castle involved more gruesome methods. In the fourteenth century one castle was subjected to an attack by having plague victims catapulted over the walls to spread the disease.
Other attacks included throwing over rotten animal bodies to spread disease and also the heads of executed prisoners!
