In a weird way, it makes sense that there are parts of this place that are blocked off? I know that in the Paris Opera House - and not the one that opened in the 1980s - from when and where I’m from, there are a lot of parts that are either not open to the public or blocked off. Usually for safety, because it’s such an old building, but there are parts of it used to transport scenery or big set pieces that aren’t open to the public.
