One thing that really stands out inside the bunker is the sheer variety of blast doors.
You’ve got the smaller fire-exit and escape doors, designed to provide a way out while still offering protection; controlled access doors, used to restrict who could enter different areas; and then the huge, heavy blast doors — solid steel structures designed to protect the bunker from the effects of an external explosion.
