How far does Hogwarts' protective enchatments extend? It protects the castle, yes. I would think it protects Hagrid's hut, right? The Black Lake? What about the Forest? Or maybe the outskirts of the Forest, to protect the Thestrals and Hippogryffs, yes?
So would there be a protective enchantment on the Shrieking Shack? Or some kind of enchantment, for any reason? Could you apparate in and out of there?
