Hogwarts är plottbar
Detta är underförstått i Fire of Fire när Hermione listar det som en taktik som används av skolorna som försöker gömma sig från utländska guider.
“There’s traditionally been a lot of rivalry between all the magic schools. Durmstrang and Beauxbatons like to conceal their whereabouts so nobody can steal their secrets,” said Hermione matter-of-factly.
“Come off it,” said Ron, starting to laugh. “Durmstrang’s got to be about the same size as Hogwarts — how are you going to hide a great big castle?”
“But Hogwarts is hidden,” said Hermione, in surprise. “Everyone knows that . . . well, everyone who’s read Hogwarts, A History, anyway.”
“Just you, then,” said Ron. “So go on — how d’you hide a place like Hogwarts?”
“It’s bewitched,” said Hermione. “If a Muggle looks at it, all they see is a moldering old ruin with a sign over the entrance saying danger, do not enter, unsafe.”
“So Durmstrang’ll just look like a ruin to an outsider too?”
“Maybe,” said Hermione, shrugging, “or it might have Muggle- repelling charms on it, like the World Cup stadium. And to keep for- eign wizards from finding it, they’ll have made it Unplottable —”
“Come again?”
“Well, you can enchant a building so it’s impossible to plot on a map, can’t you?”
“Er . . . if you say so,” said Harry.

Som kan ses, använder Hogwarts olika tekniker för att gömma sig.
Ett annat bevis på Hogwarts plottability är förekomsten av Marauders Map. Hermione säger i bok 6 att anledningen till att kravet på rummet inte finns på kartan beror på att rummet är oförstörbart. (Självklart innebär att resten av slottet är plottable.)
“I think it’ll be part of the magic of the room,” said Hermione. “If you need it to be Unplottable, it will be.”
