Many don't look up and miss the beauty of the ceiling. These castles usually have a nice ceiling, especially the ball rooms or the important ones.
I wonder if the King or Queen didnt have some cushion material on thier thrones. It would have been uncomfortable taking a seat for awhile.
Who knows, maybe they have pillows to sit on. In any case, even 30 minutes on that throne or those chairs seems like severe punishment to me 😂
In the Schönbrunn palace in Vienna, there were ropes all over, only the narrow path was for visitors. It's frustrating, but I can understand them too as there are so many people acting in a barbaric way, you have no idea. Imagine those things are 100 - 200 years old. Once broken, it's not the same anymore. Obviously the number of visitors is much higher there. I did not mind wearing these shoe covers, although it was hot. All for a good cause and I could go near everything and take some photos, even if some of them is crap, due to the furniture arrangements.
Many things can be missed by not looking in all directions. It's always important to give yourself ample time when visiting places like this.
I can understand why things are not allowed to be touched. Your absolutely correct once broken it's historic value is lost. I will say seeing something really great in a glass case is a bummer especially near too much light. I'd rather have it roped off. Than again the pieces need to be protected.
