As you might already know, I am currently working on a TV show which films at a castle outside of Vienna, Austria. What is interesting about this castle is that it was built in the 19th century on the ruins of a demolished medieval castle. The current structure is sort of frankensteined from authentic looking castle bits, purchased all over Europe.
This makes it amazing as a filming location. It look great, but it isn't a protected historical site. Film crews are like a stampede that leave a trail of destruction and water bottles. Hopeful our crew will be a little kinder to the environment than most (fingers crossed).
