How castles were built and financed in medieval times and how it’s done today

One question we get a lot from our readers and during our tours is, “how were these great castles built and financed?” Not only are people curious about how it was done in medieval times. Some have also discovered that it can be done today, and follow up with that, wanting to know more. 

We hope you’ll be as intrigued as they are when they get to know the answers.

Castles in medieval times


During medieval times, kings would order castles to be built, usually for the protection of their kingdom from possible revolts and outside dangers. They would commission a great swath of different craftsmen, from carpenters and blacksmiths to quarrymen and stonemasons.


Needless to say, the costs of the great castles and fortresses were immense. In modern currencies, they could be anywhere between $5,000,000 and $125,000,000, based on materials, size, location, logistics, and other such factors. 

Castles today


These days, castles are not being constructed as much as they were in the past. There is no longer any need for great fortresses to fend off enemies (despite how tempted one might be to ward off their neighbor). It is possible, though, to buy castles – for a hefty sum, of course. So if you’ve got the means, how cool wouldn’t it be to live like a lord or a lady? 

More often than building castles, people buy existing ones so that they may refurbish them and make them habitable. They may be meant for homes, but hotel businesses are also quite eager to get their hands on them, as they are quite exclusive and appealing. Many museums also choose to showcase their exhibitions in castles. 


When it comes to financing a castle in modern times, we reached out to several mortgage experts. We got many interesting answers, and an especially informative account from Ingvild Aagre, editor in one of Norway’s more innovative services when it comes to comparing loans.

Ingvild has specialized knowledge of loans and personal finances, and has also visited the Caernarfon castle several times, which makes her view on the matter particularly interesting. Here is what she wrote in her email: 

“The idea of living like a wealthy aristocrat in a great castle is no longer as impossible as it once was. For some people, the dream is quite achievable, although it does take quite the capital. To buy a castle today, one would need to have a very strong income, and might have to consider several financing options. 

For the castle itself, a mortgage would be a natural choice. In the ongoing process, though, a hefty amount of refurbishing is usually needed, which might make a personal loan more fitting. 

Financing a castle is not that different from financing a home, and the basics are the same. So for those of your readers who would actually be interested in getting their own castle, it may prove to be extra useful, not just as a reference, but as a guide…” [The email continues a bit further, but we got the most important points across]

Thanks to Ingvild for that thorough and explanatory answer! If you want to learn more from her about financing, perhaps not a castle, but a house and its inventory, you should check out her articles within the category forbrukslån fra Lån for deg. It contains some of the most up-to-date principles of personal loans, which are usually needed when furnishing a home. Their website is only in Norwegian at the moment, however we see that about 30% of our website visitors are from Norway, so hopefully it’s a page with some value to you. 

Now you know a little bit more about how castles were built and financed in medieval times, as well as how it’s done today.
