One of the things that has always struck me about castles is how small the rooms are. There are two main reasons for this. The first, and most obvious, is that building a castle was incredibly expensive. The reasons for the cost were that it took time, sometimes more than a decade, and sometimes imported stone was used. The masons who built castles were very skilled and demanded a higher rate of pay than ordinary labourers, who were also required.
The second reason is that castles didn’t have to be large. Even a small castle put awe and fear into the hearts of the local populace. The largest building many people knew was their parish church. Even a small castle would dwarf a church.
Another reason why they didn’t need to be large was because there wasn’t very much, apart from people and stores of food and fuel, to put into it.
People in the Middle Ages had few possessions, unless they were fabulously rich. If you could afford to build a castle, you fell into that category. The things that you might have, however, wouldn’t necessarily take up a lot of space. An expensive horse, for instance, wouldn’t need any more space than an ordinary horse. Tapestries were a good way for a man to show his wealth, but they hung from a wall, at least while the lord was in residence. He might own a few jewels, a few gold or silver chalices and good quality knives, but none of these needed much more space than cheaper versions of the same thing. A wealthy man probably had a few books. They would need to be kept securely in a locked chest to prevent theft.
Apart from tapestries and jewels, the main thing that a wealthy man had that most others in a castle (or anywhere else) didn’t have was a bed and a chair. At the top of the post I’ve put a photograph of the reproduction furniture in the hall of the Medieval Merchant’s House in Southampton. It’s not a castle by any means, but it will give you an idea about medieval furniture. There’s one chair. At mealtimes everyone sat on benches like the one you can see in front of the table. The table was a trestle table, which could be taken down and stacked against a wall when it wasn’t in use at meal times. The same thing applied to the bench. Unless they were sitting as part of their employment or at meal times, people mostly stood. If they were allowed to sit, they probably sat on a stool like this.
The stools could also be folded and put away when not in use.
Few people in a castle had beds. Most of the household slept in the hall. The lord had a bed in his solar and there might have been another bed for important visitors. When the lord moved on after spending two or three weeks in his castle, the bed would be dismantled, put on a cart and taken to the next place.
There were cupboards to store the lord’s gold and silver cups, if he had any, and clothes were kept in chests or on rails along walls. There wasn’t much need for interior space in a society that didn’t even know what privacy was and lived, for the most part, communally.
There are many things that still baffle me about castles, though, not least the question about where knights and soldiers kept their armour. They slept in the great hall, or some other communal space. Their armour and their weapons were expensive and couldn’t be folded up out of the way. Nothing that I’ve read or seen gives any indication about where these were stored. If anyone knows, please tell me.
