Similarly, what would happen if a Muggle found Hogwarts?
No they cannot. They can certainly go to the area that Hogwarts is geographically, but even if they were staring straight at it, they would not see it. If a muggle looks on Hogwarts, all they see is a dilapidated building with a sign that says “danger do not enter, unsafe”. Hogwarts is also unplotable.
