Even when you think you already know quite a lot about a topic, sometimes you still come across popular TV documentaries that still show you something new.
This five part series on experimental archeology building an entire 13th century castle is really quite impressive. There’s not any big groundbreaking discoveries being revealed, but to me it includes lots of little insights into how things were actually done in the Middle Ages and especially in the actual realities of medieval industry. It’s a little gold mine in ideas how to make your fantasy villages more than just the Generic Medieval Farming Village that you run across all the time.
I very much recommend watching it to anyone interested in what medieval life probably looked like.
