I didn't know that, my daughter read the entire history, fascinating. it was raided, robbed and burnt so many times during the past, it has a very nice history.
However, it has been restored and now is in good enough shape to be visited. Amazing how they buit these castles using every centimeter of the cliff was built on. You don't realize that unless you see pictures from above. See mine, attached. I also have drone videos if interested, just let me know.
