Ash Of Sin: Adventure Guard

Some places may be walked upon, but never changed.
Adventure Guard defines protected areas through three configurable lists:
dimensions, structures, and features.
Players who enter them are automatically switched to Adventure Mode, while every form of block breaking, placing, explosion damage, piston movement, mob destruction, and even command modifications such as setblock, fill, and clone is blocked.
Their previous game mode is restored once they leave.
The world remains exactly as it was first seen — you are a witness, not a builder.
