Here are a few good movies and websites that our students have really enjoyed in the past. The movies show the behind the scenes, disgusting jobs of Medieval Times. Some of the jobs consist of taking off a knights armour after they have been in battle for 8 hours with no bathroom breaks to their medicine people who used worms to cure a sore throat.
These websites show current castles forsale around the world. This is a great instructional tool because it shows that really old castles are still standing today and what the current cost would be. You may need to convert the currency.
