One of my absolutely favorite new shows this summer was The Quest. It was a fantasy based reality show where the paladins had to complete a set of challenges to keep from being eliminated.
It features a valley and castle where all modern devices have been somehow disappeared. Even when are in a remote location, you can still see power lines and other modern devices.
It also features a Castle that was actually in working order. I’ve been to more than one castle. Either they have been modernized or they have significant problems. Usually they are missing roofs and doors. I was astounded to see a castle where there were beds, furniture, and seemed to be someplace you can actually live in. (Presumbley, the contestants had modern bathroom plumbing that was off camera.)
It appears that it was filmed in Austria. So it actually might be a period castle and not a set. Hmm… I will have to do more digging on this. 🙂
