The Medieval Castle

The castle was a fortified building or set of buildings used to provide permanent or temporary protection and accommodation for kings and queens or important noblemen and their families. The term castle usually refers to stone buildings constructed during the Medieval period. The castle provided the centre for political and administrative power for the region.

The noblemen did not stay in the same castle all year round but tended to move from place to place depending on where their attention was required. Each nobleman and especially a king had a lot of people also travelling with him.

The castle had to provide enough accommodation for the nobleman or king and his party when they stayed at the castle. When the king was elsewhere just the number of people required to look after the castle and to guard it actually lived there.


Timber Halls

Before stone castles were constructed, many Norman barons and Saxons theges lived in wooden halls. These halls varied in size and were designed like a church is today with internal columns that supported the large timber rooves. These columns divided the length of the hall into sections known as bays. The safest place to be was this large timeber hall and so the whole household of the lord, including his family and supporters lived together within it. Bays were partitioned off and animals could also be housed within the hall.


Gatehouse to a motte and bailey castle

The majority of Norman barons, including the Kings, built small forts made from wood consisting of a strong perimeter palisade set on a high bank surrounding the bailey where the buildings for the household were located. Outside the fort a deep ditch was dug which was sometimes filled with water. Most of the time these forts were a sufficient means of defence, but if attackers got over of through the palisade there was nowhere for the defenders to retreat to. To overcome this limitation the keep was developed. The keep was a particularly strongly built building made of wood and later stone. Further developments in castle design saw the keeps built on top of large mounds called mottes.

Stone Keeps

The stone keep was at the heart of the castle and was the most fortified part having several floors and strong defences. The introduction of keeps resulted in the separation of living areas for the King or Lord and his family away from their servants

There was a range of accommodation in a castle for the range of people who lived in it. The King and Queen would have had the most comfort having private chambers in the keep. As well as chambers for the King, the keep had a 'great hall' used for banquets and meetings. Below the hall were large rooms where the knights and the king's guards would have slept and eaten. Most people would have slept on the floors rather than in beds and all in the same large room. There was not much privacy. Some castles did not have a central keep but had strong towers built along the curtain walls. One or more of these towers would have been used in place of the keep.

Accommodation was provided for the castle workers in the bailey. The bailey is the area inside the castle walls.


In a few castles the kitchens were built in the keep but in most castles the kitchens were in buildings outside in the bailey. When the king or lord was staying in the castle there would have been plenty of banquets and plenty of guests to feed. The kitchens had to be large and they had to have large fireplaces over which all the food was cooked. This included whole oxes or pigs which were roasted on spits over the open fires. Vegetables and stews would be cooked in large pots over the fires and they would have baked a lot of bread.

Store rooms

In normal times most of the food and drink used in the castle would have been supplied fresh from the surrounding land but anything that needed to be stored was kept in store rooms. Stored rooms can commonly be found on the lowest floor of the keep. Because the walls of the keep at its base are at their thickest and the windows are only small slits that let little light in the rooms at the base of the keep were kept cool even in summer. Also, because the main entrance to the keep was on a higher floor, there was no access to the store room from outside the keep and this helped protect the supplies. Supplies were important when the castle was under siege and the more supplies a castle had, the longer it could hold out.

The Lowest Floor




Most castles had a dungeon to hold prisoners and the dungeon needed to be escape-proof. In the diagram below the dungeon is built into the lowest floor of the castle and the only way into it would be through a trap door from the floor above. The prisoner would be lucky to have a small window to let some light in.

The First Floor



The Castle Entrance

The entrance to the keep of the castle was usually on the first floor and not at ground level. This made it easier to defend as a drawbridge could be used. When the King or Lord was in residence his best knights could sleep and eat in this area guarding their master at all times.

Toilets or Garderobes

Toilets were simply holes in the floor that emptied through passages in the walls out into the moat or ditch around the castle. Designers of the castle had to be careful that attackers could not enter the castle through the toilet and so even the toilets were protected, either by making the holes too small to get through or too high to reach.

The Great Hall

The great hall was were all the important meetings and banquets took place. Everyone eat at long tables sitting on benches apart from the nobles who would have had chairs to emphasise their importance. The nobles, their family and important guests would sit at the high table. Banquets would have taken hours with large numbers of courses of meat. Servants would serve the food.

The well

A castle needed to have its own water supply. This was because in the time of a siege when it was not possible get supplies the people in the castle were assured of at least water to drink. Without fresh water the castle would have been forced to surrender much more quickly. Wells were constructed inside the castles, sometimes inside the keep itself so that the keep could be held against the attackers even if the outer walls of the castle had fallen.


As horses were the main method of transport in medieval times it was important to have them kept safe within the castle walls.
